Overview

Found during the day coiled around gorgonians, sponges or in dark recesses of the reef. At night spreading their arms to face the current to feed on planktonic animals.

Sea Stars have remarkable regenerative powers, when attacked and damaged by predators they are able to grow new arms. They usually have five arms but have been found with 4 or 6 arms, this may be because more than one arm has been damaged at one time!
They possess a cleverly evolved arsenal of hydraulic tube feet connected to an elaborate water-vascular system that encircles the animal's mouth and extends via five radial canals down the centre of each arm.
Their mouth is underneath, but their prey is absorbed outside their mouths by forcing out their digestive organs from their stomach.
Sea Stars are carnivores and feed on almost any food including molluscs, worms, detritus and each other!
Some sea stars like the crown of thorns can be venomous.
