Talk:Agnatha

From Wikipedia, the free encyclopedia

My apologies for rewriting the page. 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
