Talk:Gas bladder
From Academic Kids
"Swim bladder" has more Google hits, but apparently it's no longer favored (see [1] (http://www.fishbase.org/LarvalBase/Glossary/Glossary.cfm?TermEnglish=gas%20bladder) or Bond's text for example), so I made an executive decision to put it under the correct term rather than the popular one.

- (...) evolved into the lungs of today's vertebrates and into the gas bladders of today's fish.
I changed "vertebrates" to "terrestrial vertebrates" to make the distinction clearer. There are (as always in nature...) exceptions: non-terrestrial vertebrates with lungs (lungfish and other fishes, sea snakes and turtles, cetaceans), and fishes without gas bladders (apart from lungfishes e.g. sharks), but these are cf. rare.
