What is the name of animal that hop?

Almost every mammal has the ability to jump (mind you anything can with some explosives) but there are a few exceptions. For example it's a well known fact that Elephants can't jump, nor can Rhinos or Hippos and even Platypi . This is mainly because the length and diameter of their legs doesn't give them enough lift to jump.

Hope this helps
