Betcha Didn't Know!: 12/26/11

Rabbits, Hares, Guinea Pigs, and Pikas are NOT rodents!
They are part of a new group called Lagomorphs.

The difference?
Rodents have 1 pair of incisors (Front wedged teeth).
Lagomorphs have a 1 pair of regular sized incisors and a smaller stubbed pair directly behind them.
