Habitat and distribution
Coral reefs are the natural habitat for hawksbill turtles. Caves and ledges around coral reefs provide resting areas throughout the day and night. They are found predominantly in the tropical reefs of Indian, Pacific and Atlantic oceans. Some are found on the Brazillian coast, southern Florida and Hawaii. Very little is known of the turtle's migration patterns.
Feeding & diet
The principal food of hawkbill turtles is sponge. They are considered omnivorous scavengers. Sea anemones and other invertebrates were also found in the stomach of some turtles.
Status
Endangered species. Under the Convention on International Trade in Endangered Species, it is illegal to import or export turtle products, kill, capture or harass hawksbill turtles.
