Granulated Sea Star (2024)

Choriaster granulatus, the granulated sea star, is a species of sea star in the family Oreasteridae, and the only species of its genus. It is found both individually and in groups, and resides in the Indo-Pacific region, the Red Sea, Fiji, and the Great Barrier Reef, at depths of up to 53 metres (174 ft) and temperatures of 24 to 29 °C (75 to 84 °F). It favours sandy habitats with rubble slopes and detritus as well as those among corals and sponges. Choriaster granulatus has a convex body and five short arms with rounded tips and is relatively large among sea stars, having a maximum radius of about 27 centimetres (11 in). It is most commonly pale pink with brown papillae radiating out from the centre, but can also exhibit colours ranging from grey to yellow and even red. It is a carnivore, having a diet of small invertebrates such as coral polyps as well as carrion. This C. granulatus sea star was photographed off the coast of Zanzibar, Tanzania.
