Sea star<br />
Echinodermata – Asteroidea<br />
Also known as starfi sh,<br />
these often brightly coloured<br />
echinoderms consist of fi ve or more arms<br />
radiating out from a central disc. The mouth<br />
and tube feet are located on the underside<br />
of its body. Sea stars can be herbivorous<br />
(plant-eating), carnivorous (animal-eating)<br />
or omnivorous (plant- and animal-eating)<br />
feeders. The stomach is pushed outside<br />
their own body through the<br />
mouth to surround<br />
the food. Once<br />
the food is<br />
digested, the<br />
stomach is<br />
pulled back<br />
into the<br />
body of the<br />
sea star.<br />
Did you know?<br />
Many echinoderms are able<br />
to regrow lost or damaged<br />
parts of their bodies, such as an<br />
arm. Some species can even grow<br />
back a complete new body from<br />
a single arm, if part of the central<br />
disc is attached.
