==Tunicate Fossils== | ==Tunicate Fossils== | ||
It's hard to find a full tunicate fossil, since its body is hard to keep in the same shape. That's why there aren't really many tunicate fossils that have been recorded. Sometimes, the spicules that come off of the Tunicate are found, and recorded as fossils, but that is the most likely way they can ever determine if there were tunicates far back. Since sponges also have spicules on their bodies, it is sometimes a confusion to whether or not the spicule has come from a tunicate or a sponge. The Yarnemia, has been recorded as a tunicate fossil, but it is still unknown.

==Tunicates: Medical cures== | |||
Surprisingly, some parts of the tunicates can be used for medical purposes. The tunicate has three types of chemicals/structures that can help prevent/ decrease cancer. Didemnins, Esteinascidin, and Aplidine all have effects on some different kinds of cancer. [http://zipcodezoo.com/Key/Animalia/Tunicata_Subphylum.asp] | |||
