Spider-crab: the distinctive features of this member of the family Arthropods

Anonim

There is no more amazing animal than the crab spider. Its habitat is deep under water, and its enormous size does not allow comparing it with other representatives of arthropods. For some people, the information that on land it is rarely possible to meet this animal will be quite reassuring, because few people want to see a real nightmare with a body of 45 centimeters long and a paw reach of eight meters. In fact, these individuals are available only to divers or scuba divers, because if the spider is thrown ashore, it will not last long. In addition to the fact that this crab has a major surprising difference in size, there are many more characteristic features.

Crab spider sheds and does not grow like the rest. If other animals take off their skin during molting due to the fact that it has become like a small child, then these will not increase in size if they do not want it. Growth occurs as follows. First, the spider drops its shell, which is hard. After that, for a short period of time, his new “clothes” are not strong and unstable. During this period, the water animal can swell if it decides that it is time to grow. Of course, it will not be possible to immediately achieve unprecedented dimensions. However, a few molts will allow him to reach the maximum length.

The crab spider cannot lose any of its limbs. In fact, this property corresponds to a very similar insect: tarantulas, poultry-eaters, black widows and the like. The crab in question will, over the course of several molts, grow a paw that it has lost for certain reasons. Moreover, these spiders are more adapted to growing limbs; they can cause molting on their own. And in a short time, their foot will be restored.

The giant spider crab does not respond to burns of sea anemones. This property allows him to hide from enemies. He only needs to get lost among the flocks of dangerous marine animals. As a rule, the animal clings to the anemone stalk. Thus, it turns out that it is not only guarded by dangerous creatures, but also hidden under the tentacles.

On the growth and size of the arthropod should say a few more words. If theoretically it is assumed that a wagon for recreation is located on the beach, then the spider-crab can easily step over it. The photos of this animal are better viewed in a comparative version, otherwise you simply will not be able to realize what dimensions it has. Please also note that few people manage to see this spider. The fact is that he prefers to hide. This is the explanation that the photos of the crab are not so many.

An ordinary person rarely succeeds in making the crab spider meet him alive. It can be seen only in photographs or in programs about nature. However, it should be noted that this spectacle will not be pleasant for everyone, as already mentioned above. Therefore, you need to think many times before trying to see a crab spider.
