15Behold now behemoth, which I made with thee; he eateth grass as an ox. 16Lo now, his strength is in his loins, and his force is in the navel of his belly. 17He moveth his tail like a cedar: the sinews of his stones are wrapped together. 18His bones are as strong pieces of brass; his bones are like bars of iron.
Moves his tail like a cedar? I admit it has been a while since I went to my local zoo, but hippos or elephants don't have a tail anywhere near that description. As far as a crocodile, It could be, but interesting never the less.
