UNDERSEA GOSSIP ? FISH TOO TALK !

A University of Auckland(New Zealand) marine scientist has created ripples by claiming that fish too communicate with each other.The scientist in question,Shahriman Ghazali,has claimed that fish communicate with noises including grunts,chirps and pops.He also discovered that even though all fish could hear not all were capable of making sound - pops and other sounds made by vibrating their swim bladder,a muscle they can contract.

Fish are believed to communicate with each other for different reasons,including attracting mates,scaring off predators or orienting themselves.

Ghazali discovered that the gurnard species had a wide vocal repertoire and kept up a constant chatter while the cod usually kept silent except when they were spawning perhaps because they used sound as a synchronization so that the male and female release their eggs at the same time for fertilization.As opposed to that,the goldfish were found to have excellent hearing but were incapable of making sound of any sort.
