In this episode we have: a chimpanzee learning how to make tools, a group of five cheetahs devising a new strategy of hunting (using decoys, how smart!), an aardvark who can dig to six meters down, cichlid fish that use their mouths as a nursery (buccal incubation) - and cuckoo catfish that add their eggs so cichlids would care for them. The babies are ruthless - they eat all cichlid babies.
Also, less than 8000 cheetahs left and two white rhinos females.
