Hawksbill Sea Turtleタイマイ

Eretmochelys imbricataCR— Critically Endangered

The hawksbill sea turtle is a coral-reef specialist found throughout the tropical Indian, Atlantic, and Pacific Oceans, easily recognized by its hawk-like beak and overlapping shell scutes. Sponges make up 70–95% of its diet, an unusually narrow ecological niche among sea turtles. Centuries of hunting for the tortoiseshell trade—an estimated 8.98 million individuals killed between 1844 and 1992—have left it Critically Endangered on the IUCN Red List.
