African spiny mice (very cute, sometimes kept as pets) can shed their skin, or at least patches of it, to get away from predators, and then grow it back pretty much as good as new. This could help researchers understand wound healing and regeneration.

See the paper in Nature.

The bellies of pygmy sharks glow in the dark (bioluminescence) – this makes it harder for predators to spot them from below, because they blend into the brighter light from the ocean surface.  This is controlled by two hormones, melatonin and prolactin.

Read the research in the Journal of Experimental Biology.

A type of plankton, called copepods, leap out of the surface of the ocean to avoid being eaten by fish. These tiny and brightly-coloured shrimp-like animals live just under the surface of the sea and can ‘fly’ 10 to 20 times the length of their body.

Some insects use mimicry to avoid being eaten – for example, a harmless hoverfly looks like a wasp. Some small mimics aren’t very good at it but they still seem to avoid being eaten by predators.
