The ascidians represent the most part of the vast (although little known and therefore appreciated) world of tunicates. Most of the ascidians are mostly confused with sponges, mostly from the observer. We will be able to easily distinguish the ascidians from the sponges since the latter, at the slightest contact, tend to close the siphons or otherwise to shrink. Many species of ascidians make a fine show of themselves thanks to the colors most often gaudy. Ascidians can be single or colonial. The violet devil ascidian is colonial ascidian with mainly cluster development.
