Tissues, Organs and Cell specialization
- Cnidarians have almost no organs and all function are basically preformed off of individual tissues. Though a very small number of cnidarians do have organs, the majority do not. (Classic Sidwell Education)
- Cnidarians also have two layers of living tissue, separated by the mesoglea, a gelatinous layer. The first layer is known as the dermis and the second layer is know as the gastordermis. (http://classic.sidwell.edu)
