Overview
Asterina gibbosa is a small cushion star, up to five centimetres across, with a rounded upper surface and very short, broad-based arms. Most have five arms, although four or six can occur. Short stiff spines cover the upper surface; brown, green and orange individuals can be mottled.
It lives beneath boulders and stones on sheltered or partly exposed rocky shores, as well as in rock pools and deeper water. The species changes sex during growth: younger, smaller individuals are male, becoming female as they grow older and larger.
