Other common names include big-plated sea star, Hunter-five Seastar and doughboy starfish.

Choriaster granulatus is a large sea star with a convex body and five short arms.

The arms have rounded tips, making it appear "phallic", leading to one of its common names being "the doughboy starfish".

[7] Choriaster granulatus has been found individually or in groups along coral reefs in the Indo-West Pacific region.

[13] The arms of Choriaster granulatus can become deformed when small parasitic limpets attach to their underside.
