Giant tunicate GALLERYMicrocomus exasperatus/Pyura Vittata
There are several types of large tunicate s that do not belong to the same genus. Here are several varieties. Just like the small tunicate s, the animal is a filter feeder. Drawing water,in through it's incurrent siphon, to extract food and oxygen then dischargeds through the excurrent siphon. They will close the siphon if disturbed, but reopen in a faily short time. They should not be confused with sponges, which do not have the ability to close their siphons. Even though tunicate s may look like very simple creatures, they each have a nervous, digestive, reproductive and a circulatory system.
