Hawksbill Turtle

Smaller sea turtle with a narrow pointed beak adapted for picking sponges from reef crevices. Common in Caribbean and Indo-Pacific reefs.

The Hawksbill Turtle (Eretmochelys imbricata) is a highly migratory species predominantly found in the warm, tropical, and subtropical waters of the Atlantic, Pacific, and Indian Oceans, typically between 30° North and 30° South latitude.

This species utilizes a variety of habitats throughout its life cycle:

• Early Life Stages: Post-hatchlings are pelagic, spending their initial years in the open ocean. They often seek shelter in floating algal mats and lines of flotsam, drifting with ocean currents.
• Juvenile and Adult Habitats: As they mature (around 20-25 cm in length), Hawksbill Turtles recruit to coastal foraging areas. They are most commonly associated with healthy coral reefs, rocky areas, and shallow coastal zones. Other important habitats include lagoons, estuaries, and mangrove swamps, particularly in the Eastern Pacific where large populations forage and nest in mangrove estuaries. They are also found in shoals, seagrass beds, and around oceanic islands.

Hawksbill Turtles are generally observed in shallow waters, with adults rarely foraging in depths greater than 20 meters. However, they are capable of diving to depths of up to 200 meters, though most of their daily activity involves shallow dives between 2–20 meters. During the day, they are often seen resting in caves and under ledges within coral reefs, frequently returning to the same resting spots night after night.

Their distinctive narrow head and hawk-like beak are perfectly adapted for extracting their primary food source—sea sponges—from crevices within coral reefs. This specialized diet makes them crucial for the health of coral reef ecosystems, as their foraging helps prevent sponges from outcompeting hard corals for space, thereby promoting reef biodiversity. While primarily spongivorous in the Caribbean, Indo-Pacific populations exhibit a more varied diet, including other invertebrates, algae, and even mangrove shoots.

Notable dive sites where Hawksbill Turtles are commonly observed include the USAT Liberty Wreck, Batu Bolong, Tatawa Besar, Mawan, Siaba Besar, Pink Beach, Sombrero Island, and Sardine Run Moalboal, indicating their widespread presence across the Indo-Pacific region.
