Extendable Jaws Gave Fish an Evolutionary Edge

Extendable Jaws Gave Fish an Evolutionary Edge

@...@Professor David Bellwood, of James Cook University, said protrusion was one of the key traits that made fish efficient hunters ©with some fish today able to extend their jaws by up to 20 per cent of their body length// **When we eat a meal we*ve got to use our hands and forks to bring the food up and push it into our mouth,** Professor Bellwood said//

@...@**What the fish can© do is take their mouth and put it on to the food// **It*s a huge advantage if you are trying to feed on something that is elusive and fast moving if you are chasing something on the bottom and you*ve got to get your whole body on to it, then it*s like smashing on to a wall//
