Hawksbill turtle Eretmochelys imbricata
Adults are typically about 1 m long and weigh about 80 kg, and sponges make up 70–95% of their diet. Critically Endangered on the IUCN Red List (Wikipedia).
Key marks: A pointed, beak-like head and thick, overlapping shell plates that give the back edge of the shell a saw-toothed look (Wikipedia).
At Roatán: The turtle divers meet most in Roatán Marine Park: 14 dive operators logged 666 hawksbill sightings on 701 dives at 46 sites in June–August 2014, and researchers watched 61 juveniles in the water (Hayes et al. 2016). Sea turtles are common on the West End Wall (Scuba Diving 2018), and one seamount, Hawksbill Bank, is named after its resident hawksbill (Divernet 2023).
