Description

The sicklefin lemon shark is a large requiem shark (Carcharhinidae) from shallow coastal and reef waters of the Indo-Pacific. The species grows to about 3.8 metres and has a robust, yellow-brown body with conspicuously sickle-shaped fins. As a slow but powerful bottom predator it hunts fish and rays in lagoons and around reefs. Due to its size and teeth it can be dangerous when disturbed; through habitat loss and fishing the species is endangered.
