My apologies for rewriting the page.this is stupid this is fucking stupid actually There was nothing wrong with it, but it was difficult to fit in all the material I wanted to add without some reorganization. Feel free to hack up whatever I did if it is unsatisfactory - DJK 20030518

[edit] I'm sorry, but

Agnatha are not fishes.They have completely different skeleton, and their notochord lasts unchanged for their whole life.

[edit] Hagfish

Hagfishes aren't really agnathans. All agnathans are jawless vertabrates whos mouthes are fixed open. A hagfish's mouth is not fixed open, they have horizontally articulating "jaws", while agnathans just have a mouth fixed open. Giant Blue Anteater 05:17, 9 September 2006 (UTC)

[edit] Cyclostomes

Hagfishes are considered agnathans because they are cyclostomes. Hagfishes belong in the Myxinidae family under the class Agnatha. Information cited from http://www.gma.org/fogm/Hagfish_Lamprey.htm |Qwertyloo

[edit] Old terminology

Agnatha is a dated term; it is being used less and less because the group is paraphyletic. This should be mentioned somewhere in the article. Fuzzform 21:42, 22 March 2007 (UTC)

Where does this one belong then? Bob the Wikipedian (talk) 23:12, 13 May 2008 (UTC)

We could describe it simply as an early craniate or chordate. —Preceding unsigned comment added by Cephal-odd (talk • contribs) 05:50, 14 May 2008 (UTC)
