Stalking salamander

Why did ancient fish leave the water in the first place on their way to becoming amphibians? The answer is food. When the first amphibians moved out of water, the land was already swarming with insects and some amphibians evolved a special weapon with which to catch them. The contraction of the muscles around its tongue is all a salamander needs to move its tongue forward and some salamanders have a tongue that is three-quarters the length of their bodies. But most salamanders still have to get pretty close to their quarry.
