The Chiton

The chiton is pretty simple. No fancy sprays of ink, no tentacles, no bright colors and I strongly advise against eating it. Its got lots of gonad, a rubbery foot, some gill filaments, a couple of plates embedded in its shell and a digestive tract (remember "MESIRA"). You'll see it on the lab practical so know it cold. If you think its not that impressive, just remember that they were around long before man and apparently their system works for them.
