What are the similarites and differences in teeth structure and function in fishes, amphibians, and birds?
Answers
AMPHIBIAN : They have what are called vomerine teeth that are only located on the upper jaw and are only in the front part of the mouth. These teeth are used to hold onto prey and not used to actually chew or tear apart prey.
FISH : Fish like chain pickerel and gar have obvious canine-shaped teeth. Other fish have less obvious teeth, such as the cardiform teeth in catfish which feel like a roughened area at the front of the mouth, or vomerine teeth that are tiny patches of teeth, for example, in the roof of a striped bass' mouth.
BIRD ; Some birds have tooth-like serrations, called tomia, that run along the edges of their bills, which help them grip food. ... Baby birds have what is a known as an “egg tooth”, a small, sharp structure on the end of their beaks, used to penetrate the shell of the egg so they can hatch.
