The video above shows the fascinating way male giraffes fight. Known as “necking” the giraffes use their long and powerful necks to attack, delivering hard blows with each hit.
At the second level, an animal performs a programmed act of behaviour, as when a prey animal feigns death to avoid being eaten. At the third level, the deceptive behaviour is at least partially learnt, as when a bird puts on a distraction display , feigning injury to lure a predator away from a nest.
For example, when predators avoid a mimic that imperfectly resembles a coral snake, the mimic is sufficiently protected. [ 26 ] [ 27 ] [ 28 ] Convergent evolution is an alternative explanation for why coral reef fish have come to resemble each other; [ 29 ] [ 30 ] the same applies to benthic marine invertebrates such as sponges and nudibranchs .
There is a strong evolutionary pressure for prey animals to avoid predators through camouflage, and for predators to be able to detect camouflaged prey. There can be a self-perpetuating coevolution, in the shape of an evolutionary arms race, between the perceptive abilities of animals attempting to detect the cryptic animal and the cryptic characteristics of the hiding species.
Giraffes have one of the shortest sleep durations among all land mammals, and according to Wildlife FAQ, "On average, adult giraffes sleep for about 30 minutes a night, and their sleep cycles are ...

Aggressive mimicry is common amongst spiders, both in luring prey and stealthily approaching predators. [18] One case is the golden orb weaver (Nephila clavipes), which spins a conspicuous golden coloured web in well-lit areas. Experiments show that bees are able to associate the webs with danger when the yellow pigment is not present, as ...
Escape response in Antarctic krill.. Escape response, escape reaction, or escape behavior is a mechanism by which animals avoid potential predation.It consists of a rapid sequence of movements, or lack of movement, that position the animal in such a way that allows it to hide, freeze, or flee from the supposed predator.
