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.
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.
Further, young giraffes are much more vulnerable to predation than adults: between 60% and 75% of calves die within a year. [12] Mothers hide their calves, which spend much of the time lying down in cover. Since the presence of a mother does not affect survival, Mitchell suggests that young giraffes must be extremely well camouflaged.
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.
Predators need not locate their host directly: Kestrels, for instance, are able to detect the faeces and urine of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example. This adaptation is essential in prey detection, as voles are quick to hide from such predators.
The U.S. Fish and Wildlife Service has proposed new protections for giraffes, saying their populations are threatened by poaching, habitat loss and climate change. Giraffes need endangered species ...
