The Granulated Sea Star (Choriaster granulatus) is a striking reef dweller. It is found throughout the tropical Indo‑Pacific, from East Africa to Fiji. It often appears in shallow coral and rubble zones between 1 and 40 meters deep.
This species has short, rounded arms. Its body is plush, ranging from pink to beige, and is covered in raised papillae. It stands out as one of the most distinctive sea stars in the region. Reaching a radius of up to 25 centimeters, it moves slowly across the reef. It is a quiet scavenger and predator. It feeds on small invertebrates and coral polyps. Yet, it remains entirely harmless to humans.

Indo‑West Pacific reefs and rubble, commonly in shallow water down to around 40 m.
