Conservation

Conservation Status

Critically Endangered

Status in Egypt

 Fairly common, but declining. The increase in tourist activities and artisanal fishing in the Red Sea is leading to growing disturbance to the nesting sites of these animals on offshore islands. Development on the mainland is reducing avail­able nesting sites. In the past stuffed animals were commonly offered to tourists, but this has subsided to a large extent.

Description

Behaviour

Carnivorous, feeding largely on sessile marine invertebrates, such as sponges and soft corals.

Ecology and Distribution

Global Distribution

A pan-tropical species, recorded erratically in the Mediterranean, but not known to breed there.

Distribution in Egypt

The Red Sea, where it is the commonest marine turtle; not recorded yet from the Egyptian Mediterranean, although Werner (1988) lists the species from Israeli Mediterranean waters. It has been recorded throughout the Red Sea and in both the Gulfs of Aqaba and Suez. Breeding has been recorded throughout the Hurghada Archipelago, Ras Mohamed, Wadi El Gemal Island, Qulan Islands, Ras Banas, and Zabargad Island.

Habitat

Warm tropical and subtropical marine waters, usually near coral reefs and rocky outcrops in shallow waters.
