[edit] fish brain

Would anyone happen to have info on fish brain? I came here to look for whether fish can feel pain or not (someone said they can't because they're missing that part of the brain). Now I don't want to write the section myself, as I obviously don't know anything about fish brains... --HJV 15:58, 16 March 2006 (UTC)

[edit] Fish - Anatomy

Can someone tell me if the following is true

Fish have very good eyesight and can see in all directions at the same time

Fish have airbag which help to stay upright


Fish that use eyesight for hunting may have good eyesight. Many fish have laterally placed eyes (on the side of their head)so they can see predators approaching. However, some fish have eyes located more dorsally (towards the top of their head). This allows them to see more in front of them. These fish may have grooves in front of their eyes, this lets them see over their nose. So for fish with dorsal eye placement and eye grooves, they have a wide viewing range. The airbag you mention is called a swim bladder. It is a sac of air that the fish can inflate or deflate depending on if they want to go up or down in the water or respond to pressure changesRanled 03:29, 20 November 2006 (UTC).

Please update the article accordingly, there are many curious people around. `'mikka 18:46, 3 April 2007 (UTC)

[edit] Fin Use

Could someone add for what each fin is used?

It varies from species to species. For example, most species use the caudal fin for propulsion, but triggerfishes use their dorsal and anal fins and wrasses use their pectoral fins. Male livebearers use their anal fins to impregnate females. Some fishes, such as knifefishes of the family Notopteridae, don't even have a caudal fin. --Ginkgo100 19:10, 26 May 2006 (UTC)

Also Please note that your article needs some info about the skelital structure. If you could provide that soon that would be helpful!

[edit] Merger proposed (Pterygiophore)

The following discussion is archived. Please do not modify it. Subsequent comments should be made in a new section.

The result was: Merge as proposed. --B. Wolterding (talk) 13:39, 6 December 2007 (UTC)

I propose to merge the content of Pterygiophore into here, since the notability of that article has been questioned. Actually the article has remained a very short stub, and the information could easily be included here.

Please add your comments below. Proposed as part of the Notability wikiproject. --B. Wolterding 14:42, 1 December 2007 (UTC)

  • Can't think of any reason why it shouldn't be merged. GrahamBould 14:59, 1 December 2007 (UTC)
  • Marge. Saintrain 16:14, 1 December 2007 (UTC)
  • Merge. It can always be broken out at a later date if it expands enough. Totnesmartin (talk) 15:56, 5 December 2007 (UTC)
