Sea Urchins

 
   
Sea urchins or urchins are small, spiny, globular animals that compose part of class Echinoidea. They are found in oceans all over the world. Their shell, or "test", is round and spiny, typically from 3 to 10 cm across. Common colors include black and dull shades of green, olive, brown, purple, and red. They move slowly, feeding mostly on algae. Sea otters, wolf eels, and other predators feed on urchins. Sea urchins are also harvested by humans and their roe is served as a delicacy.Sea urchins are members of the phylum Echinodermata, which also includes sea stars, sea cucumbers, brittle stars, and crinoids. Like other echinoderms they have fivefold symmetry (called pentamerism) and move by means of hundreds of tiny, transparent, adhesive "tube feet". The pentamerous symmetry is not obvious at a casual glance but is easily seen in the dried shell or test of the urchin.

A great choice for the aquarium, urchins are excellent detritus (left over food), and aquarium algae eaters, and they like live rock that they can crawl on. At night, they will roam about the entire tank searching for food and algae on the substrate, rockwork, and glass. All urchins are completely reef-safe.

Food and diet:The urchin is best kept in an aquarium where it will have ample supplies of algae to eat. In the absence of enough algae, food can be placed near its spines or even on them. The spines have the ability to transport the food to its mouth. Use care when handling any urchin, as the spines are sharp and may break-off into your skin.
