Hawksbill turtle (Eretmochelys imbricata)

Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

Eretmochelys imbricata is one of the smaller turtle species, with a carapace (shell) of up to 1 m and weighing up to 80 kg. The beak-shaped mouth has lead to the species common name of hawksbill. The carapace of this species is amber in colour with reddish-brown, blackish-brown streaks and can also have yellow markings.

Recorded distribution in Britain and Ireland

With such few recordings, this species could be considered a vagrant in UK waters.

Habitat

Hawksbills use different habitats at different stages of their life cycle. Adults are usually not found in shallow marine habitats (unless coming ashore to nest), whereas small juveniles are rarely far from the shallowest coral reefs in tropical waters and therefore unlikely to be found in the British Isles.

Identifying features

  • Up to a 1 m in length and weigh up to 80 kg.
  • Carapace is amber streaked with reddish-brown, blackish-brown and yellow markings.
  • Mouth is beak-shaped.

Additional information

Populations of hawksbill are threatened with decline as a result of a number of factors, including loss of nesting sites, accidental entanglement in fishing line and the destruction of coral reefs which provide a feeding ground.
