description Clypeaster speciosus Overview
Clypeaster speciosus is a species of sea biscuit, a type of irregular sea urchin belonging to the family Clypeasteridae. Inhabiting sandy marine environments across the Indo-Pacific region, this echinoderm features a heavily calcified, flattened test designed for burrowing beneath the substrate. Unlike regular sea urchins, it lacks prominent defensive spines and relies on its structural shape to navigate and anchor in the sand. It functions as a deposit feeder, processing sediment to extract organic nutrients.
