Scientists have discovered that sea lice have two body clocks: one which follows day/night circadian rhythms and another which follows the tide which rotates every 12.4 hours. This additional body clock allows the sea lice (Eurydice pulchra) to burrow at low tide and then return to the surface to feed when the tide returns.
In the wild, chimpanzees use a unique set of visual gestures in order to communicate with one another.

This article and video highlights the unique methods which cuttlefish use in order to catch fish. Recently discovered by researchers, the cuttlefish transform their body shape and coloration in order to appear like a hermit crab. This becomes advantageous as hermit crabs do not hunt fish and therefore appear harmless to fish. Researchers suspect that this mimicry is a foraging behavior which allows them to catch more fish as fish do not sense a threat.
The birds-of-paradise exhibit extraordinary displays when attempting to attract a mate.
