Why are elephants so fat?

no seriously this is no joke...do you think they evolved from triceritops? like seriously, look at that thing on a tricereitops, its sorta like the elephants ears, but put together, and then they got the horns, like the elephant, but the 3rd tusk is the trunk. and there bodies are the same...!?!?! I mean c'mon? y??? tell me!!!!!!

Why are elephants so fat?
It's called Bergmann's Rule. Elephants evolved from earlier forms, like mammoths and mastodons, which both lived in cold regions. Having a rotund body minimized the ratio of surface area to volume. That way, they could retain body heat more easily. But elephants live in the tropics, you say? They can survive because of Allen's rule, which correlates the size of appendages with the heat of the environment. Modern elephants have much larger ears than mastodons or mammoths had. The thin, well-vascularized ears act as a radiator to get rid of the excess heat. Ain't nature grand?
Reply:Elephants are not fat. If they stood only a few feet tall then yes, they would be fat, but you have to remember that some can reach 13-15' tall. Even then the bulk of their body is muscle and bone, not fat/blubber. Also remember, that overall muscle weighs more than fat so that also adds to the pounds.





As far as having evolved from triceratops, nope, not even close. Plus.... I think you are forgetting about mammoths.
