African/Zoo animals in the US

[rob]

I had a couple of thoughts on this tread yesterday, one on Hippos, the other on Elephants. Both being mammals, both would develop more body hair and/or body fat to keep warm (like seals and whales). Both are herbivores, with Hippos finding food on land or in a body of water, most likely a river, and Hippos being ill tempered when encroached upon, have killed humans in Africa. Elephants would mainly be of the Indian species, some maybe of the African species, or a hybrid of both (it has happened before). Perhaps the elephants are mutating more in a Mammoth or a Mastodon species, with cross breeding abilities. Just thoughts.
