"all craniates have skulls"
Surely this isn't true? -see hagfish Fayefox 20:37, 27 February 2007 (UTC)
someone shouold add the link to http://zh.wikipedia.org/wiki/%E5%85%A8%E5%A4%B4%E7%B1%BB
Hagfish spp. actually do have skulls, which are made of cartilage. They do not, however, have vertebrae, which is why they are considered craniates but note vertebrates. I added references attesting to the hagfish skull and generally including hagfish among the craniates. As for the recommendation to add a link to the Chinese language article, this appears to pertain only to Holocephali, a subclass of Chondrichthyes. Holocephali, and all chondrichthyans, are craniates, but these two articles are not equivalent because the Chinese article deals exclusively with one subclass.

[edit] "Craniata includes all animals with a head"
In common parlance, "head" designates the business end of various non-craniate animals, such as the cephalic tagma of insects. For clarity, perhaps change either to "all chordates with a head" or "all animals with a cranium"? —Preceding unsigned comment added by 85.8.12.78 (talk) 11:29, 22 December 2007 (UTC)
