Alluring crab: description and photo


Varieties of crabs are very many. Some use in cooking, but not more than seven species. The rest quietly live in nature. All of them have different appearance, size and color.

Crabs are huge, from a meter to three in length, and there are small, like an alluring crab. He is considered one of the most interesting representatives of his family.

Crab habitat

The enticing crab lives in a colony of the same crustaceans as he. He is very loyal to his neighbors, which is not the case with strangers who entered his territory.

Ordinary crabs can be found anywhere, but alluring is found in the western side of the Atlantic Ocean and Africa. This creature is accustomed to a specific climate, warmer. Therefore, it can be found at the bottom of the Indian and Pacific Oceans. The attracting crab is also found here, you can meet him in Russia.


Appearance Description

These creatures are very small. The body reaches a size of about 2.5 cm, with claws up to 10 cm. But more often they can be found smaller. They look like ordinary crabs - head with breast and belly, divided into segments. Alluring crab (photo below) has a durable shell that protects it. But he still has a peculiarity - this is a very large right claw. Because of her, he moves strangely, as if he is luring, hence his name.

The length of the claw can reach the length of the whole crab body. The left one remains the usual size. This feature is only in males. The claws of females are the same. This huge male claw has several uses. For example, an inviting crab scares off enemies from itself, protects its housing and attracts females. He does everything else with his left limb, for example he eats.

These crabs have a regenerative function. They are able to re-grow their huge claw, if for some reason it has disappeared. After a certain period of time, it will grow back, and may also increase in size relative to what it was before. In the period when the right claw is still small, the crab tries not to crawl out of its mink, so as not to endanger itself.

The fiddler crab is another name for the enticing crab. In the mating season, this representative of the fauna actively begins to move its claw, which resembles playing a violin. Crabs like aktivnichat in the evening or at night, when it is completely dark. In this case, their claw is not visible. Therefore, the crustaceans start knocking it on the ground or trees, thereby luring females. Thanks to such a large limb, the crab locks the entrance to its home during sleep, so that no one can climb to it.

Yellow-white-red claw perfectly stands out against the background of bright short-tail crab. Crabs can be gray, red or black. Having a small size, the crab becomes noticeable due to its color. He may be blue, but, having such a claw, he can always protect himself.

During the breeding season, the male tubules are filled with germ cells and fertilize the female openings. After that, the female fastens the formed eggs to itself on the legs and carries them to hatching.
