Everyone knows that every representative of the faunanature has awarded certain mechanisms of protection against threats that come from the external environment. And animals with needles are remarkable in this respect. Some of them are so "insured" by attacks on the part of living beings, which pose a serious danger even for human health.
It should be noted that animals with needlesare characterized by the fact that they have a dense prickly layer of skin, so it is almost impossible to reach their vulnerable spots. They also carefully protect the "bare" areas, when the danger immediately collapses into a tangle.
So, which animals with needles are the most protected from the unfavorable conditions of the external world?
First of all, this is Australian echidna.Her needles can hurt anyone who comes too close to her. The size of echidna corresponds to the size of the hare. If you distract the animal while it eats, it immediately burrows into the ground in such a way that only protruding needles will be visible, and will remain in that position until the troublemaker is gone. Also, in order to protect the echidna, it can, like the hedgehog, curl up into a ball, it has sharp needles even on its paws. Total on her body there are more than 5 thousand spines.
What other animals with needles are reliableprotection mechanisms? These include a lizard-battleship, which lives on the island of Madagascar. This reptile has spiky rigid plates, which cover most of its body. She uses her "weapons" in two ways. On the tail of the spikes perform the function of protecting the burrow. If a threat arises from anywhere, the animal puts its tail in its mouth, thus transforming itself into a "spiked" wheel. To cope with such an obstacle is far from being available to every representative of the fauna.
What is the name of an animal with needles, whosethey are thick, long and always thrown back? For sure, every child knows the answer to this question. Of course, it's a porcupine. He is also perfectly "armed" in order to resist external stimuli. As soon as a threat arises, he immediately straightens his thorns and begins to shake his tail, issuing a gnashing, which is more like the hiss of a snake.
In the event that such a warningthe enemy did not react, then in the next instant the animal releases the needles directly into the face of the offender, who, ultimately, whatever power he possessed, is forced to retreat, since the risk of being spiked with poisonous spines is very large.
Which animals with needles have increasedprotective immunity, swimming in the sea? Among them you can distinguish a porcupine fish, which is also called a sea urchin. His needles are deadly. In their natural state, the thorns of the water dweller are "smoothed" along the body. At the slightest suspicion of danger, he immediately absorbs a huge amount of water, his needles become "on end" and the sea urchin turns into a big spiny ball.
This is an additional confirmation of how unusual and surprising the representatives of fauna can be.
