Mokele-mbembe

Mokele-mbembe is a largest species of pangolin on earth, about twice the weight of a white rhinoceros. It might look like a surviving Apatosaurus at first glance, but people most likely mistaken a large mammal for a diplodocid that is thought to be extinct in the mesozoic, and not just that, it has fur like almost all mammals, gives birth to live young and feeds its young its milk like all mammals, it has scales like other pangolin species, and it has mammalian teeth. It feeds on insects, leaves, and fruit. It is indigenous to rainforests of Central Africa and Western Africa. One reason why they feel threatened by hippos is because hippos are the most dangerous mammals of Africa and can sometimes kill young Mokele-mbembes, so Mokele-mbembes protect their own kind from dangerous animals, including hippos.
