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. |

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"? |

"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"?
