Swim bladders and the "Barry White of the Sea"

Here is the link to the NY Times story I mentioned in class a few lectures ago on vocalizations made by fish using their swim bladders.  The article highlights several cases in which obnoxious noises were assumed to be anything BUT made by fish and those who suggested fish as the culprits were called crazy!  As I mentioned the swim bladder is thought to be evolutionarily homologous to the early lung and both develop as outpockets of the gut (in the early stages of development). A paper by Zheng et al., published in 2011 in PLoSONE looks at some of the evidence for the "homolog" idea, and their results "provide molecular evidence of the relatedness of the fish swimbladder and mammalian lung."

Here also is the link to some of the cool sounds fish make, including the "Barry White of the sea", the black drum.

And one more link: this one describing research by SFSU professor Roger Bland on the vocalizations of the toadfish in SF Bay.
