Animal teeth
Animals'
teeth are different depending upon what foods they eat.
Meat-eaters
(carnivores) have sharp teeth.
Plant-eaters
(herbivores) have flat teeth.
Animals
that eat both plants and meat, like humans, have sharp teeth in front and
flat teeth at the back.
Sharks lose teeth each week. They get
new teeth when they lose the old ones. They may have over 20,000 teeth in a
lifetime.
Crocodiles
have 60
teeth in their mouth at any one time and can grow up to 2-3,000 teeth during
their lifetime.
Poisonous
snakes have
hollow fangs which eject poison.
Giraffes
have 32
teeth, just like humans.
Elephants
have
four sets of teeth in their lifetime. Their tusks are the longest teeth in
the world.
Dolphins
have
more teeth than any other animal. Some dolphins have over 200 teeth.
Scientists can tell the age of a dolphin by the rings on their teeth.
Snowshoe
rabbits
fight with their teeth. Adult males, called bucks, fight one another with
their teeth when they court the females or does.
Baleen
whales don't
have teeth. Instead they have stiff, fringed plates, made of the same stuff
as human hair and fingernails. They hang down from the upper jaw and trap
small fish and other food.
