Everyone knows that each representative fauna nature endowed certain mechanisms of protection against the threats that originate from the external environment.And quite remarkable in this respect animals with needles.Some are so "insured", he attacks from beings that are dangerous even for human health.
It should be noted that animals with needles are characterized by having a dense layer of prickly skin, so to reach their vulnerabilities is virtually impossible.They also carefully guard "bare" areas, in the event of danger immediately curling up into a ball.
So what animals with needles are protected against the most adverse conditions of the outside world?
On land
is primarily short-beaked echidna.Its needles can cause pain to anyone who approached her too close.The size corresponds to the size of vipers hare.If divert the animal at the time when it is eating, it immediately bury in the ground in such a way that can only be seen protruding needle, and will stay in this position as long as troublemaker leaves.Also, in order to protect the viper can, like the hedgehog, curl up, it has a sharp needle even on foot.Total on her body there are more than 5 thousand thorns.
What other animals with needles have a reliable protection mechanisms?These include the armadillo lizard, which lives on the island of Madagascar.This reptile has a prickly rigid plates, which cover a large part of her body.His "weapon" it applies in two ways.At the tail spines carry out the function of protecting the burrow.If there is any danger from the animal's tail he puts in his mouth, thus transforming "spike" wheel.To cope with this obstacle is the strength is not each representative fauna.
What is the animal with the needles, which are thick, long, and always pulled back?Surely the answer to this question is known to every child.Of course, this porcupine.He is also well "armed" in order to resist external stimuli.As soon as there is a threat, he immediately straightens his thorns and begins to shake a tail, uttering at the same grinding, which is more like a hissing snake.
If at this warning his opponent did not react, then in the next instant, the animal releases the needle straight into the muzzle of her abuser, who in the end, no matter what power he possessed, forced to retreat because the risk of being pricked by poisonousspines very large.
in water
What animals with needles have an increased protective immunity, swimming in the sea?Among them are the porcupine fish, which are also called sea urchin.Its needles are deadly.In its natural state thorns inhabitant of water "combed" along the body.At the slightest suspicion of danger, he immediately absorbs a huge amount of water, its needles become "stand on end" and sea urchin turns into a big spiny ball.
This is another proof of how unusual and can be surprising fauna.
