Laniakea Beach Oahu: Where Hawaiian Sea Turtles Come Ashore

Laniakea Beach isn't just another sandy cove on Oahu's legendary North Shore—it's Hawaii's most reliable spot to witness one of the island's most sacred and enchanting creatures: the Hawaiian Green Sea Turtle, known locally as Honu. Nestled between Haleiwa and Sunset Beach along scenic Kamehameha Highway, this unassuming stretch of sand has earned the affectionate nickname "Turtle Beach," and for good reason. On any given afternoon, you might spot 5 to 15 of these magnificent creatures hauled out on the beach, resting, thermoregulating, and soaking up the sun—an experience that connects visitors directly to Hawaii's marine ecosystem and cultural heritage.

This comprehensive guide explores everything you need to know about Laniakea Beach and the incredible Honu that make it a must-see destination on any North Shore tour. From the biology and behavior of these endangered turtles to their profound significance in Hawaiian culture and the remarkable conservation success story, we'll dive deep into the world of Hawaiian Green Sea Turtles and what it means to be a responsible, respectful visitor to their habitat.

Location, Access & Quick Facts

Laniakea Beach is located on the North Shore of Oahu along Kamehameha Highway (HI-99), situated between the town of Haleiwa to the south and Sunset Beach to the north. The beach is immediately adjacent to the highway, making it one of the most accessible wildlife viewing spots in Hawaii.

What You'll See

On a typical day at Laniakea Beach, you're likely to see multiple Hawaiian Green Sea Turtles resting on the sand or in shallow water. The beach is monitored by volunteers who maintain rope barriers to protect the turtles from human disturbance. Educational signage explains the species' biology, conservation status, and viewing rules. During peak season (spring and early summer), sightings are nearly guaranteed.

Meet the Honu: Hawaiian Green Sea Turtles

The Hawaiian Green Sea Turtle is not just any sea turtle—it's a genetically distinct population that has called Hawaiian waters home for millennia. Known as Honu in Hawaiian, these ancient mariners represent a conservation success story and a living connection to Hawaii's natural and cultural heritage.

Species Identity & Naming

The Hawaiian Green Sea Turtle is scientifically known as Chelonia mydas, a species found in tropical and subtropical oceans worldwide. However, the Hawaiian population is genetically distinct from other green sea turtles, having evolved over thousands of years in isolation. This unique population is endemic to Hawaii and is protected under both the U.S. Endangered Species Act and Hawaii state law.

The name "green sea turtle" is often misunderstood—it doesn't refer to the color of the shell, which is typically brown or olive in Hawaiian waters. Instead, it derives from the greenish color of the fat beneath the turtle's shell, an adaptation related to their primarily herbivorous diet.

Size & Physical Characteristics

• Adult Weight: 200–500 lbs (typically females are larger than males)
• Carapace Length: 2.5–4 feet
• Lifespan: 60–80+ years (some individuals may live even longer)
• Sex Determination: Temperature of sand during incubation determines sex; warmer temps = females
• Color: Brown, olive, or reddish shell; lighter plastron (underside)
• Flippers: Two front flippers, two hind flippers; streamlined for swimming

Diet & Feeding Behavior

Hawaiian Green Sea Turtles transition from omnivorous hatchlings to primarily herbivorous adults—a dietary shift that reflects their ecological niche in Hawaii's marine ecosystem. Adult Honu are voracious consumers of limu (Hawaiian seaweed) and sea grasses, including limu manauea, ogo, and other algae species found in coastal waters. They can eat up to 10% of their body weight in seaweed daily, making them important regulators of algal growth in Hawaii's reefs and coastal zones.

Young turtles, however, eat jellyfish, crustaceans, and other invertebrates as they develop. This dietary transition is gradual and takes several years. Adult turtles have been observed eating small fish and sponges opportunistically, though seaweed comprises the bulk of their diet.

Behavior & Basking

One of the most distinctive behaviors of Hawaiian Green Sea Turtles is their practice of hauling out on shore to bask in the sun—a behavior that makes Laniakea Beach such a special viewing destination. Unlike most sea turtle species that rarely come ashore except to nest, Hawaiian Green Sea Turtles regularly leave the ocean to rest on beaches and rocky areas.

Why do they do this? We'll explore basking behavior in detail later, but the key is thermoregulation—warming their bodies, facilitating digestion, removing parasites, and obtaining essential rest from the ocean environment.

Cultural Significance: Honu as Aumakua

For Native Hawaiians, the Honu is far more than an endangered sea turtle or a tourist attraction—it is a sacred, integral part of Hawaiian culture, spirituality, and history, revered for thousands of years.

Aumakua & Family Guardians

In Hawaiian belief, Honu serves as an aumakua (family guardian spirit or ancestral guardian). An aumakua is a deified family ancestor who takes the form of an animal and protects and guides family members. Families with Honu as their aumakua believe the turtle watches over them, providing guidance, protection, and spiritual connection to the ocean and their ancestors. This relationship is reciprocal—families respect and protect Honu in turn.

Observing proper protocol when encountering a Honu is not just about endangered species conservation; it's about honoring this spiritual relationship and showing respect to Hawaiian culture. This is why maintaining distance, avoiding disturbance, and following viewing guidelines are so critical—they're rooted in cultural protocol as much as ecological necessity.

Kauila the Turtle Goddess

Hawaiian mythology features Kauila, a goddess associated with turtles and the ocean. While Kauila is sometimes depicted as a female turtle herself, her legend emphasizes the connection between human and marine life, and the sacred trust between people and the ocean's creatures. Different versions of Hawaiian legends present variations, but the consistent theme is the reverence for turtles as divine, wise beings worthy of protection and respect.

Historical Abundance & Recovery

Archaeological evidence and historical accounts suggest that Hawaiian Green Sea Turtles were far more abundant in pre-contact Hawaii. However, during the 19th and 20th centuries, unregulated hunting, egg collection, and environmental degradation drove the population to near extinction. The fact that Honu are seen at Laniakea Beach today is directly due to legal protections enacted since the 1970s—a recovery that honors both the cultural and ecological significance of these animals.

The Conservation Success Story

The story of Hawaiian Green Sea Turtles is, in many ways, a beacon of hope in conservation—a rare example of a species brought back from the brink of extinction through dedicated protection, legal frameworks, and community involvement.

Historical Decline

By the 1970s, Hawaiian Green Sea Turtle populations had declined dramatically due to:

• Hunting for meat and shells (traditional, commercial, and subsistence)
• Egg collection for food
• Accidental capture in fishing nets (bycatch)
• Habitat loss and coastal degradation
• Pollution and marine debris
• Loss of nesting beaches to development

By the 1970s, populations had crashed to unsustainably low levels. The remaining wild turtles were concentrated at a few feeding grounds in the Hawaiian Islands and a few nesting sites in the Northwestern Hawaiian Islands, particularly French Frigate Shoals.

Legal Protection & Recovery

In 1978, Hawaiian Green Sea Turtles received federal protection under the U.S. Endangered Species Act, followed by protection under Hawaii state law. These legal frameworks prohibited:

• Hunting and harvesting of turtles
• Collection or disturbance of eggs
• Destruction of habitat
• Harassment or harm to turtles

The law has teeth: violations can result in significant fines (up to $100,000) and imprisonment. Importantly, the law also protects nesting beaches and adjacent areas critical for turtle breeding and nesting.

Remarkable Population Growth

Since protection in 1978, the Hawaiian Green Sea Turtle population has increased by approximately 53%, a remarkable recovery that demonstrates the power of legal protection when combined with habitat management and public education. Current estimates suggest approximately 12,000–13,000 Hawaiian Green Sea Turtles exist in the wild, though population monitoring continues to refine these numbers.

This recovery is particularly noteworthy because it occurred despite ongoing challenges including climate change, ocean acidification, pollution, and diseases like fibropapillomatosis (discussed below). The increase in sightings at beaches like Laniakea is a direct result of this recovery—and a visible testament to successful conservation.

Ongoing Challenges

Despite the success, Hawaiian Green Sea Turtles remain threatened by:

• Climate Change: Rising ocean temperatures affect nesting beach conditions and marine ecosystems
• Marine Pollution: Plastic debris, fishing line, and other trash injure and kill turtles
• Light Pollution: Artificial beach lighting disorients hatchlings attempting to reach the ocean
• Diseases: Fibropapillomatosis and other diseases continue to affect populations
• Fishing Bycatch: Despite regulations, some turtles are still caught in fishing gear
• Loss of Seagrass Habitat: Coastal development and sedimentation reduce feeding habitat

Ongoing research, habitat restoration, disease monitoring, and continued legal protection remain essential to sustaining this recovery.

What You'll See at Laniakea Beach

When you arrive at Laniakea Beach, here's what a typical experience looks like and what you might observe:

The Beach Setup

Laniakea Beach is a crescent of golden sand bordered by homes and small commercial areas along Kamehameha Highway. Unlike some other beaches, Laniakea typically has maintained rope barriers—often in the form of simple PVC or fabric rope—that create a perimeter around resting turtles. Educational signage explains the species, viewing guidelines, and the importance of maintaining distance.

Volunteers are often present, especially during peak season, to educate visitors, answer questions, and help ensure compliance with viewing protocols. These volunteers are invaluable resources for learning more about the turtles and their behavior.

Typical Turtle Activity

On an afternoon visit, you might observe:

• Basking Turtles: 5–15 individuals hauled out on the sand, often arranged along the waterline or slightly inland, resting motionless or moving very slowly
• Aquatic Resting: Additional turtles in very shallow water, heads occasionally poking above the surface to breathe
• Color Variations: Shells ranging from olive-brown to nearly black; some individuals showing barnacles, algae, or scarring from past injuries
• Size Differences: Adults of varying sizes; occasionally younger individuals (sub-adults) interspersed with adults
• Individual Behaviors: Some turtles sleeping; others periodically shifting positions or flippers; some individuals more alert than others

Environmental Setting

Laniakea Beach itself is relatively small and can become crowded during peak tourist season. The view includes the iconic North Shore horizon, with Diamond Head visible in the distance on clear days. The water is typically clear, and the sand is warm—conditions that explain why turtles find the beach so appealing for basking.

Seasonal Variations

While turtles can be seen year-round at Laniakea, seasons do influence abundance and behavior:

• Spring–Early Summer (March–June): Highest turtle abundance, males actively seeking mates, best time for sightings
• Summer–Fall (July–September): Good sightings but fewer turtles than spring; some individuals migrate to other feeding grounds
• Fall–Winter (October–February): Fewer turtles visible, though still possible; some individuals offshore or at other locations

Turtle Viewing Etiquette & The Law

Seeing a Hawaiian Green Sea Turtle in the wild is an unforgettable privilege—and with that privilege comes significant legal and ethical responsibility. Understanding and following viewing guidelines protects turtles and ensures the experience remains sustainable for future visitors.

The 10-Foot Rule (Federal Law)

Under federal law (Endangered Species Act) and Hawaii state law, you must maintain a minimum distance of 10 feet from any Hawaiian Green Sea Turtle at all times. This rule is absolute—no exceptions.

What's Prohibited

Federal and state law explicitly prohibit:

• Touching: No hand contact of any kind
• Chasing or Cornering: Deliberately following or blocking a turtle's path
• Flash Photography: Using camera flash (can disorient or stress turtles)
• Picking Up Young/Hatchlings: Even with intent to "help" (illegal and harmful)
• Feeding: Offering food or drinks (turtles are herbivorous; inappropriate foods can cause serious harm)
• Noise & Disturbance: Loud noises, sudden movements, or deliberate disturbance
• Swimming Near: Approaching turtles in the water
• Blocking Paths: Standing between a turtle and the ocean or its resting area

Penalties for Violations

Violating these protections carries serious consequences:

• Civil penalties up to $100,000 per violation
• Criminal penalties including fines and potential imprisonment
• Confiscation of cameras or equipment used in violation
• Potential revocation of marine recreation permits or licenses

These aren't empty threats—NOAA Fisheries and Hawaii Department of Land and Natural Resources actively enforce these protections, and violations have resulted in significant fines.

Best Practices for Respectful Viewing

Basking Behavior: Why Turtles Come Ashore

One of the most fascinating aspects of Hawaiian Green Sea Turtles is their habit of hauling out on shore to bask in the sun—a behavior that distinguishes them from most other sea turtle species worldwide. Understanding why turtles bask enriches your appreciation for what you're witnessing at Laniakea Beach.

Thermoregulation

The primary reason Hawaiian Green Sea Turtles bask is thermoregulation—maintaining optimal body temperature. While turtles are cold-blooded ectotherms, they're not passive to temperature; they actively seek conditions that allow them to maintain a comfortable, physiologically optimal temperature range (typically 25–28°C / 77–82°F for Hawaiian Green Sea Turtles).

Basking in the sun allows turtles to:

• Warm Their Bodies: Direct solar radiation transfers heat to the turtle, raising core body temperature
• Facilitate Digestion: Warmer body temperatures speed digestion of their algae-based diet, improving nutrient absorption and metabolic efficiency
• Enhance Activity: Warmer muscles function more efficiently, improving mobility and response times
• Regulate Seasonal Patterns: Seasonal temperature changes help cue reproductive and migratory behaviors

Parasite Removal

Basking also helps turtles remove parasites, algae, and other organisms from their shells and skin. The warm sun may help dislodge external parasites, and the terrestrial environment is less hospitable to some marine parasites, providing temporary relief. Additionally, sand abrasion as turtles move and settle can help remove attached organisms.

Rest & Recovery

The ocean, while home, is an active, energy-demanding environment. Basking provides an opportunity for deep rest and recovery. Turtles ashore exhibit relaxed, low-activity states—essentially napping in the sun—conserving energy for swimming, feeding, and other essential behaviors. This rest is particularly important for reproducing adults and growing juveniles.

Immune Function & Vitamin D Synthesis

Solar exposure may also support vitamin D synthesis and strengthen immune function, though research on sea turtle-specific vitamin D metabolism is still ongoing. The combination of warmth, rest, and solar exposure likely supports overall health and disease resistance.

Behavioral Adaptation to Hawaiian Waters

Interestingly, Hawaiian Green Sea Turtles are unique among global Chelonia mydas populations in their propensity for hauling out to bask. Turtles in other regions (e.g., Atlantic or Indo-Pacific populations) bask much less frequently or not at all. This behavioral difference likely reflects adaptation to Hawaii's specific environment—warm, shallow coastal waters; abundant feeding grounds near shore; and beach conditions that make hauling out energetically feasible. This unique behavior is one reason Laniakea Beach and similar locations are so special for turtle viewing.

The Great Journey: Migration & Nesting

While many visitors see Hawaiian Green Sea Turtles basking at Laniakea Beach and assume these are local residents, the reality is far more complex and remarkable. The turtles you see represent participants in an epic transoceanic journey spanning hundreds of miles and multiple decades.

Feeding Grounds vs. Nesting Grounds

The vast majority of Hawaiian Green Sea Turtles spend most of their lives in feeding grounds scattered throughout the Hawaiian Islands—places like Laniakea Beach where abundant seaweed and kelp provide constant food sources. These feeding grounds are where individual turtles reside for months or years, growing, reproducing (in the case of adults), and maintaining their populations.

However, female turtles don't nest in Hawaii. Instead, they migrate to the Northwestern Hawaiian Islands, particularly French Frigate Shoals, located over 500 miles northwest of Oahu. This extraordinary migration represents one of the longest migrations undertaken by any reptile.

The French Frigate Shoals Nesting Ground

French Frigate Shoals—a remote atoll system within the Papahānaumokuākea Marine National Monument—hosts the only significant nesting population of Hawaiian Green Sea Turtles. Females return to these islands every 2–4 years to nest, laying eggs in sandy beaches on protected islands within the atoll system.

Why do females migrate so far to nest? Several theories exist:

• Optimal Nesting Conditions: French Frigate Shoals offer sandy beaches with specific temperature and sand composition ideal for egg incubation
• Predation Refuge: Remote, protected islands offer reduced predation risk for eggs and hatchlings
• Genetic Fidelity: Females return to the beaches where they themselves hatched (natal philopatry), perpetuating this migration route
• Evolutionary History: This migration pattern likely developed over thousands of years of adaptation to Hawaiian conditions

The Breeding Cycle

The reproductive cycle of Hawaiian Green Sea Turtles is characterized by:

• Slow Sexual Maturity: Females don't reach breeding age until 30–50 years of age (some studies suggest even older)
• Intermittent Breeding: Once mature, females breed every 2–4 years, producing 1–5 clutches per breeding season
• Large Clutches: Each clutch contains 80–120+ eggs buried in the sand
• Incubation Period: Eggs incubate for 50–60 days in the warm sand, with hatchling sex determined by sand temperature
• Hatchling Emergence: Tiny hatchlings (about the size of a coin) dig out of eggs and scramble to the ocean, a perilous journey with high mortality
• Years at Sea: Hatchlings spend 5–10+ years in the open ocean before recruiting to coastal feeding grounds

Pelagic Years: The Lost Decade

One of the greatest mysteries in sea turtle biology involves the "lost years" or "pelagic years"—the period when juvenile turtles disappear into the open ocean after hatching. During this time, young turtles drift in ocean currents, feeding on jellyfish, sargassum seaweed, and other pelagic organisms, growing slowly in the vast expanse of the Pacific.

Very little is known about this phase of life. Turtles during this period are incredibly vulnerable to predation, starvation, pollution, and storms. It's estimated that fewer than 1 in 1,000 hatchlings survive to adulthood—a staggeringly low survival rate that emphasizes why protecting nesting beaches and hatchling habitat is so critical.

After 5–10+ years, juvenile turtles somehow locate and recruit to coastal feeding grounds, including those in Hawaii, where they spend decades of their adult lives feeding and resting at locations like Laniakea Beach.

The Turtle You See May Carry Ancient Journeys

This means the Honu you observe basking at Laniakea Beach may have:

• Spent years drifting across the open Pacific as a juvenile
• Arrived at Hawaiian feeding grounds as a teenager or young adult
• Spent decades (20–50+ years) residenting in Hawaii
• If female and mature, undertaken the perilous 500-mile migration to French Frigate Shoals to breed multiple times
• Survived diseases, predators, fishing nets, pollution, and storms across its 60–80+ year lifespan

Witnessing such an ancient, well-traveled creature is, in essence, witnessing a living chronicle of the Pacific—a direct link to forces and journeys that dwarf human experience and timescale.

Fibropapillomatosis: A Growing Threat

While visiting Laniakea Beach, you may notice some turtles bearing unusual growths—bumpy, tumor-like protrusions on their skin, flippers, or around their eyes. These are indicators of a disease called fibropapillomatosis (FP), a significant and growing threat to Hawaiian Green Sea Turtle populations.

What Is Fibropapillomatosis?

Fibropapillomatosis is a disease characterized by the proliferation of benign tumors (fibromas and papillomas) on the skin and eyes of affected turtles. The disease is caused or associated with herpesvirus (possibly one or more turtle-specific herpesviruses, including Chelonid Herpesvirus 5—CHV5), though the exact etiology remains an area of active research.

Prevalence in Hawaii

Fibropapillomatosis has increased dramatically in Hawaiian waters over the past few decades. Prevalence rates in some Hawaiian turtle populations are estimated at 5–50%, with some feeding areas showing higher infection rates. This is considerably higher than in other sea turtle species and populations globally, making Hawaii a unique case study for FP.

Impacts on Affected Turtles

The disease impacts turtles in several ways:

• Visual Impairment: Tumors around eyes can obscure vision, impairing feeding and predator avoidance
• Feeding Interference: Oral or flipper tumors can impede feeding efficiency
• Mobility Reduction: Flipper fibromas can restrict movement and swimming efficiency
• Immune Stress: Chronic viral infection consumes immune resources, reducing ability to fight other infections
• Reproduction: Infected turtles may have reduced reproductive success
• Mortality: Severe cases can be fatal, particularly in young or immuno-compromised individuals

Research & Management

Researchers are actively investigating FP through:

• Epidemiology Studies: Understanding transmission routes, risk factors, and prevalence patterns
• Viral Characterization: Identifying and characterizing the viruses associated with FP
• Hatchery Programs: Managing disease in captive breeding and head-start programs
• Treatment Research: Exploring potential therapies and immune-boosting interventions
• Environmental Factors: Investigating whether pollution, habitat degradation, or climate change increase susceptibility

While there is currently no cure for fibropapillomatosis, understanding the disease's ecology and improving habitat quality and water conditions may help reduce transmission and support immune function in wild populations.

Other Hawaiian Sea Turtles: Honu'ea & Others

While Hawaiian Green Sea Turtles dominate at Laniakea Beach and most Hawaiian beaches, other sea turtle species inhabit Hawaiian waters, though they're far rarer.

Hawksbill Turtles (Honu'ea)

Hawksbill Sea Turtles (Eretmochelys imbricata), known as Honu'ea in Hawaiian, are occasionally found in Hawaiian waters but are extremely rare compared to Green Sea Turtles. Hawksbills are smaller (adults typically 2–3 feet), have distinctive beak-like jaws, and are specialized sponge eaters. They are critically endangered globally, with Hawaiian populations representing only a tiny fraction of their former numbers. Honu'ea sightings are exceptional; if you see one, consider yourself extraordinarily fortunate.

Leatherback Turtles

Leatherback Sea Turtles (Dermochelys coriacea) are pelagic deep-ocean dwellers that occasionally pass through Hawaiian waters. They're the largest sea turtles (up to 1,500+ lbs) and are immediately distinctive due to their leathery skin and lack of a bony shell. Leatherback sightings in Hawaii are rare but do occur, particularly in deeper offshore waters.

Loggerheads & Others

Loggerhead Sea Turtles and other species are extremely rare in Hawaiian waters, though occasional individuals have been recorded, primarily from outside the islands.

The rarity of non-Green Sea Turtles in Hawaii emphasizes just how special Hawaiian Green Sea Turtle populations are and how critical their protection is to maintaining sea turtle diversity in the Pacific.

Best Time to Visit Laniakea Beach

Optimal Season

Spring through early summer (March–June) is the absolute best time to visit Laniakea Beach for sea turtle viewing. During this period:

• Turtle abundance is at its peak, often 10–15+ individuals on the beach simultaneously
• Males are actively seeking mates, increasing activity and visibility
• Water conditions are improving (warming up after winter)
• Weather is generally stable and pleasant

Time of Day

Afternoon (2–5 PM) is ideal for turtle viewing. Turtles are most active during warm afternoons when solar radiation is strongest. Morning visits are possible but less reliable. Evening is acceptable but not optimal as turtles may be returning to the water for the night.

What to Expect by Season

• Winter (Dec–Feb): Fewer turtles (they may migrate to other locations), cooler weather, variable ocean conditions. Turtles still present but sightings less guaranteed.
• Spring (Mar–May): Peak season—maximum abundance, most reliable sightings, warm weather, calm water often.
• Summer (Jun–Aug): Good sightings, high heat, occasional summer swells, tourist season in full swing (can be crowded).
• Fall (Sep–Nov): Moderate sightings, cooling temperatures, hurricane season begins (late Aug–Nov), fewer tourists.

Weather Considerations

• Avoid High Surf Days: Large winter swells (Dec–Feb) can wash out the beach or create dangerous conditions; surf forecasts are available online
• Avoid Strong Wind Days: Wind can make viewing difficult and stress turtles; calm conditions are ideal
• Check Tide: Low to mid-tide is often best; at high tide, turtles may be in deeper water
• Avoid Storms: Turtles often retreat to deeper water or stress during severe weather

Avoiding Crowds

Laniakea Beach can become extremely crowded during peak season and tour bus hours (typically 11 AM–3 PM). If you prefer fewer crowds:

• Arrive early (9–10 AM) or later (after 4 PM)
• Visit on weekdays rather than weekends
• Visit during shoulder season (Feb–March or June–July)
• Avoid high tourist season (June–August, December holidays)

Frequently Asked Questions

Q: Are the turtles safe to touch?

A: No. Touching is illegal and prohibited under federal law. Maintain 10+ feet at all times. Touching stresses turtles, disrupts their essential behaviors, and can cause legal penalties up to $100,000.

Q: Can I swim with the turtles?

A: Not at Laniakea Beach. The turtles here are resting on shore and should not be disturbed. In other locations (like Shark's Cove), passive observation from a distance is sometimes possible, but active swimming toward turtles is prohibited.

Q: Why do turtles bask on the beach?

A: Turtles bask for thermoregulation (warming their bodies), to facilitate digestion, remove parasites, and obtain rest. It's an essential behavior for their health and survival.

Q: What's the difference between male and female turtles?

A: Visual sex determination is difficult in the field. Males typically have longer tails and concave plastrons (underside); females are usually larger. Females are the ones that migrate to French Frigate Shoals to nest.

Q: How long do sea turtles live?

A: Hawaiian Green Sea Turtles typically live 60–80+ years, with some individuals potentially living longer. They're among the longest-lived reptiles.

Q: Are turtles endangered?

A: Yes. Hawaiian Green Sea Turtles are listed as Threatened under the U.S. Endangered Species Act. While populations have recovered about 53% since protection in 1978, they remain vulnerable to pollution, climate change, disease, and human disturbance.

Q: What if I see an injured or sick turtle?

A: Contact the Hawaii Department of Land and Natural Resources (DLNR) or NOAA Fisheries immediately. Don't approach or attempt to help on your own; trained professionals are needed.
