Beavers

  The Canadian beaver also known as the "super beaver" lives in some parts of Alberta and BC.
the beaver is a large help to the wild life of Alberta, they keep the water in bound and keeps the marshlands fresh with new mud.
  The Canadian beaver is known to be the smartest animal engineer of the world.
Unlike most animals, the crocodile and the beaver didn't change much from 63 million years ago. They fairly stayed the same except for the size of the animal, which became far more smaller than what it is now.
  The beavers of north america were almost extinct by the 20th century, but in 1998 a pair of canadian beavers raised in captivity were released in the wild to mate and reproduce.
  By now almost 500 beavers are tagged in the alberta region.
