Honolulu Sea Turtles: A Guide to These Ocean Dwellers
Honolulu sea turtles, primarily the green sea turtle (Chelonia mydas), are a common and beloved sight along the shores and in the waters surrounding Oahu. These gentle creatures are often observed basking on beaches or gracefully swimming in the reefs, offering a unique glimpse into Hawaii’s rich marine ecosystem. Understanding their behavior, habitat, and conservation status is crucial for ensuring their continued survival.
Green Sea Turtles in Honolulu
The green sea turtle, known locally as “honu,” is the most frequently seen sea turtle species in Hawaiian waters. They are characterized by their smooth, heart-shaped carapace (shell) and their herbivorous diet as adults, which contributes to their greenish-colored fat. Juvenile green sea turtles are omnivorous, feeding on small invertebrates in addition to algae and seagrass.
Where to Spot Sea Turtles in Honolulu
Several locations around Oahu are known for sea turtle sightings. Popular spots include:
- Laniakea Beach (Turtle Beach): This beach is famous for turtles basking in the sun.
- Hanauma Bay: While snorkeling, you might spot turtles feeding on algae.
- North Shore Beaches: Various beaches along the North Shore offer opportunities for turtle sightings.
It’s important to maintain a respectful distance from the turtles and avoid touching them. Regulations require a minimum distance of 10 feet.
Conservation Status and Threats
Green sea turtles are listed as threatened under the Endangered Species Act. While populations in Hawaii have shown signs of recovery, they still face numerous threats, including:
- Entanglement in fishing gear: Turtles can become entangled in nets and lines, leading to injury or drowning.
- Habitat loss: Coastal development and pollution can degrade nesting beaches and feeding grounds.
- Boat strikes: Turtles can be injured or killed by collisions with boats.
- Disease: Fibropapillomatosis, a disease causing tumors, affects sea turtle populations globally, including in Hawaii. More information about Fibropapillomatosis in sea turtles can be found on Wikipedia.
