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.
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.
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.
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 those long necks — so it stands to reason that sometimes things will fall out of place. Standing on a platform high above the ground, Whitley slowly manipulated the giraffe's neck ...
Island tameness can be highly maladaptive in situations where humans have introduced predators, intentionally or accidentally, such as dogs, cats, pigs or rats, to islands where ecologically naïve fauna lives. It has also made many island species, such as the extinct dodo or the short-tailed albatross, vulnerable to human hunting. In many ...
Two giraffes, Asiwa and Easter, have now made the aquatic escape and the organizations are working to save the remaining six. Rothschild's giraffes are becoming a rare breed, with around 3,000 ...
While animals performing distraction displays are rarely documented as being killed, risks to the displaying animal do exist. [33] One researcher observed and documented an instance in which a second predator became attracted to an animal already performing a distraction display. The displaying animal was killed by the second predator. [33]
