text: Actually, most fish do have teeth, but the number varies greatly depending on what kind of fish you're talking about, what species, and even what age the fish.  The numbers go from zero to tens of thousands.\n\nFor example: The great white shark has 46 teeth in its Front Row Dentition, but there are any number of teeth behind each of those teeth ready to take their place should the front tooth be lost.  The cownose ray usually has seven series of teeth on their dental plate in each jaw.  Each series has 11 to 13 rows exposed and functional at any one time, fitted into an interlocking pavement of hexagonal, pentagonal and tetragonal shaped flat grinding surfaces.  \n\nSome fish not only have teeth along their jaws, but also in the bones on the roof of their mouth (vomerine teeth), and along gill rakers.\n\nFor rabbits, most of them have 2/1 incisors (2 top, 1 bottom), 0 canines, 3/2 premolars and 3/3 molars for a total of 28 teeth.  One genus(Pentalagus - the Amami rabbit found only a small island off Japan) has one fewer upper molar on each side, so they have only 26 teeth.\n\nIn toads, the number of teeth is also variable depending on species, but in most the number of teeth is set for each species.  It is often used as a characteristic to define a species.  Often the teeth of many frogs and toads are very small, barely more than spicules, and not easily visible to the naked eye.
