Their mean and moody expressions suggest: Go on, punk, make my day.

With its opponent on the floor, it does not hesitate to put the furry boot in as it protects its particular part of a camp site in Etosha, Namibia.

They are poor climbers and tend to live in interconnecting burrows, which they sometimes share with mongooses.

The rodent uses its bushy tail to shield it from the sun and pumps it up and down as an alarm signal to other members of the pack.

When, that is, it isn't beating the living daylights out of the neighbours.
