Coatonachthodes ovambolandicus is a termite-mimicking beetle which lives as a parasite in their nests.
This less than accurate emulation can be explained by looking at the beetle from the side rather than down at its dorsum.
The beetle's head and leg-bearing thorax are minuscule relative to its large abdomen.
The rear end thus acts as the termite 'head', and its appendages (legs and antennae) are composed of moving flaps attached to the abdomen's upper side.
In Climbing Mount Improbable, Richard Dawkins describes this imitation as "one of the most astonishing spectacles in all natural history.
