Choriaster granulatus is a large seastar, and is easily identified by its five distinctive large, short, thick conical arms. [2] It is usually pale pink in colour, has small, brown papillae in clusters located in the central part of its body. [2] This species grows to a maximum radius of approximately 27 cm.[3]
This species is found in numerous tropical waters, including:[3]
Choriaster granulatus lives in shallow waters at depths of up to 40 metres,[5] and is found on rubble slopes, coral reefs,[3] in the reef front, back reef, the external reef, and frequently in locations with rubble and detritus.[2]
This starfish feeds on algae, detritus, and dead animals.[2] One of its predators is the sea snail Triton's trumpet (Charonia tritonis).[3] It also eats various small invertebrates and coral polyps.[5]
