A mixed martial arts fighter received an offer of £370,000 to fight a chimpanzee, with warnings about life-changing harm.

Cole Johnson said the initial joke became an actual bout.

The event looked to have been called off after its website was taken down over trust and safety.

It was later described as a crypto hoax.

Separately, nine chimpanzees on Ngamba Island selected a baited box on 73 percent of trials when a human pointed, called names, and food-grunted.

Pointing alone did not produce the same result.
