It’s hard to write this up as Mr. Nature, because the Nandi Bear might not exist. But it’s been a staple of East African folklore for a very long time, and I am told there are people in Kenya who are absolutely sure the beast is real–and very much to be avoided.
It is described as something between an oversized hyena and an undersized bear. As far as scientists can tell, bears have never lived in Africa south of the Sahara. Ice Age hyenas were much bigger and stronger than today’s hyenas, and they ate mammoths and rhinos. Eating a human wouldn’t pose much of a challenge.
Is it possible that an incredibly rare, powerful, nasty relative of the hyena prowls the forests of Kenya? People do sometimes attribute unidentified, fatal animal attacks on humans to the Nandi Bear. Hard to study an animal when no one who ever sees it lives to tell the tale.
And then there’s the basic problem of cryptozoology: no specimens. Because if you do come up with a specimen–like when fishermen first caught a coelacanth–it immediately ceases to be cryptozoological and becomes just plain zoological! What’s a poor cryptozoologist to do? His situation is impossible.
