Common Starfish

The common starfish have a bizarre eating habit; they feed by forcing their membranous stomachs out through their mouths and secreting enzymes that digest the food, which is transported to the gut by special hair-like cilia. The common starfish is normally 10-30cm. They can grow to a maximum diameter 50cm. Common starfish vary in colour; through they are usually orange, pale brown or violet.

They have five tapering arms that turn up at the tip when active. Tube feet allow the starfish to cling on to rocks in wild conditions. Severed arms may be capable of becoming new individuals. Their habitat varies and includes coarse and shelly gravel and rock. Starfish are active carnivores.
