Tunicates, more often called Ascidians or sea squirts, are the only animals that perform cellulose biosynthesis. Normally thatís strictly the domain of plants.
Most tunicates are hermaphrodite and there are over 4000 species.
As you can see on this page, they are often hard to determinate.

F. and C. Monniot, 2001, almost all
Atriolum robustum are actually Didemnum molle. The real A. robustum is then only found below 40 meters. However, these A. robustum miss the network of internal channels and the secretion of sticky mucus that D. molle has. For now, I keep them as two separate species.
