New Discovery: Deep Sea Fish Have Ears!!!
 
I never really wondered if fish had ears or not, but in a recent discovery scientists found fish in the deep end of the waters that evolved ears like no others. Examining several fish species collected from waters as deep as 1.6 miles (2.5 kilometers), researchers discovered ear structures never seen before in other fish.The strange structures may enhance the animals hearing, researchers speculate.
The inner ear (pictured) of a blue antimora (inset) is exceptionally rigida feature never before seen in a deep-sea fish, according to a study to be presented in May 2009.
