Hawksbill turtle
Eretmochelys imbricata
Hawksbills often work reef cracks with their narrow, hawk-like beak, but some populations live in mangrove estuaries and feed in very different ways.
Critically Endangered (IUCN, 2008) means it is at extremely high risk of extinction in the wild.
Photos show the species, not always the places on this page.
Length
Shell (carapace) usually about 0.6 to 1.07 m (2 to 3.5 ft) long
Weight
Usually about 45 to 68 kg (100 to 150 lb); up to about 90 kg (200 lb)
Next to a person
Next to an adult, the shell is roughly knee-high to waist-high
What it eats
On coral reefs often mainly sponges, plus algae, corals, molluscs, tunicates, crustaceans, sea urchins, small fish and jellyfish. The diet differs by place; in the Eastern Pacific some also eat mangrove seeds.
Around people
Calm, give space
How it lives
The hawksbill uses its narrow, pointed beak to pick sponges and other food from cracks in the reef. Many travel between feeding and nesting grounds, but distances differ by population. Females nest every 1 to 5 years, laying 3 to 5 nests of 130 to 160 eggs in a season, and turtles take 20 to 35 years to become adults.
Where it goes
Many hawksbills migrate between feeding areas and nesting beaches, and females return to nest every 1 to 5 years. In the Eastern Pacific, many use mangrove estuaries and make shorter trips. Tracked females in the western Caribbean swam about 434 to 619 km from Utila and Tortuguero to feeding areas, and one female from Buck Island, US Virgin Islands, was tracked about 1,867 km to the Miskito Cays, Nicaragua.
Populations
About 2,000 hawksbills nest each year at the Arnavon Islands in the Solomon Islands, about 2,000 in Indonesia and about 1,000 in Seychelles. Around the Gili Islands, 51 hawksbills were identified from photos in 2019, and about 150 since 2016. Around Amed and Tulamben in Bali, hawksbills are common.
Meet it respectfully
Never touch, chase, feed, surround or block a turtle, and let it choose how close to come. Keep encounters short and quiet. We keep at least 3 m (10 ft) from turtles and follow local park rules, which differ by place. Never buy tortoiseshell products.
Fun fact
Tap the bulb to light it up.
Hawksbills eat sponges that are toxic to most other backboned animals.
Some Eastern Pacific hawksbills live in mangrove estuaries and even eat mangrove seeds.
The hawksbill is on CITES Appendix I, the highest level of protection from international trade.
In the Caribbean, hawksbills eat almost nothing but sponges. Their meals hold more silica, a natural glass, than any other vertebrate's diet, so one study called it a diet of glass.

Hawksbills eat sponges that are toxic to other vertebrates. They are one of fewer than a dozen backboned animals known to specialise in sponges.

A hawksbill that nested at Buck Island, US Virgin Islands, was tracked about 1,867 km (1,160 miles) to its feeding area in the Miskito Cays of Nicaragua.
