About

The common sunstar is a type of starfish, with 10-12 short arms that look like sun rays. It has an orangey-red disc (the centre) with beautiful concentric bands of yellow, orange, pink or white. The sunstar is an echinoderm - which means "spiny skinned" and it lives up to the name as it is covered in small spines. It lives on the seabed in shallow waters close to the shore as well as down to depths of 50m. Small sunstars are sometimes found in rockpools, so keep an eye out next time you're at the beach.

How to identify

The common sunstar is usually orangey-red in colour with concentric bands of yellow, pink, red or white on the arms. It is sun-shaped, with more arms than other starfish: normally 10-12, but occasionally 8-16.

Distribution
