Hi, I think that the hippopotamus is not able to jump either. http://en.wikipedia.org/wiki/Hippopotamus

Sloths don't jump either. They sometimes fall when they climb on fragile branches, and their backs are made for that, but they don't do it intentionally.

African elephants can jump. There is a annual 'Elephant Jumping Festival' held in Nairobi. Hippopotamuses, whales and giraffes, however, cannot jump.

The answer to your question is no, elephants cannot jump, despite what one answer has told you, their knees would simply collapse under the great weight of landing such a thing. But they are not the only animals that cannot jump; hippopotamus'; Giraffe's; Cows; Pigs etc

No.

Remember tortoises? And terrapins at their most athletic fall into water from ledges.

Very large animals have pillar-like legs partly because muscle strength increases with cross-section, quadratically, while mass increases with volume, cubically, so neither their weight nor leg shape suits jumping. Elephants' legs are not even adapted for running, though they can shuffle faster than humans can run.

Also, cracks grow readily in large bones; elephant bones are rigid, while mouse bones are flexible. Accordingly, really heavy animals like rhinos and hippos can hardly jump or land without injury. Even at matching terminal velocity, mice would bounce where elephants would break.

Still, don't jump to optimistic conclusions if a large animal chases you over a ditch; does it count as "being able to jump" if one may expect a jump to cause injury, or the action of jumping is unnatural and upsetting?

If so, then you may be in trouble because yes, Indian elephants can jump. J.H. Williams in his book "Elephant Bill" related how a stampeding cow jumped a ditch very handily, though she went dead lame in both forefeet soon after.

Still, if you happen to believe the story about Elephant Jumping Festivals in East Africa, I could book seats for you at £1000 each.

Enjoy your anticipation!
