Phryne are unique in that they have six walking legs, while other spiders have eight. The reason for this is that the first of zhgutonogie spiders arachnids changed walking legs in the senses. These long sensitive tentacles can be twice as long as the body and are used for environmental studies.

Another distinctive feature is their pedipalps as claws. These structures act as prehensile limbs normal or mantis shrimp mantis. Phryne use them to catch prey, which they then crushed their mouthparts tentacles so called chelicerae.

As Phryne active in conditions where gets very little sunlight, these modified legs are very important to them as a tool for learning.

Currently Systematics allocate 5 families, 17 genera and 136 species of Phryne, who live around the world in tropical and subtropical countries. About them a lot of rumors and tales written many European and American writers. The reason for this was very unusual, and their complete absence in temperate countries.

Phryne were at all times incomprehensible and unpleasant to ordinary people, so many of them moves tales. In some places, home zhgutonogie spiders, local residents are afraid of them and consider them extremely dangerous. For example, during a stay in the Seychelles in 1872, one biologist, local residents said that after the bite Phryne body edema, convulsions and vomiting, and that if the victim is not treated with ammonia, it will eventually lead to long-term illness or death.

Even brought to Europe to inspect samples of these spiders, some scientists fear, so great was their prejudice. One of the first authors who described Phryne, saying that they can do to a man seriously injured with pedipalps, which can even lead to death after being bitten.

Yet no matter what wrote about these creatures, but they are completely harmless. Phryne unable to bite or otherwise harm a person. Zhgutonogie spiders are not poisonous, and their menacing pedipalps are used solely to capture small prey, such as tiny insects crawling on the trunks of trees.

Even today, the media did not take any action to debunk the myth that Phryne dangerous to humans. For example, in the film version of “Harry Potter and the Goblet of Fire,” zhgutonogie spiders are described as “deadly” animals, damned-seeing eye. Phryne are rare guests on television because of its unusual “shocking” appearance. In the show “Fear Factor”, participants were forced to eat these creatures, proving that people are much more dangerous to zhgutonogih spiders than they are for us.

Sometimes these fights turn into a real fight, and males clasp each other and pushing. Fights end when one of Phryne runs from the battlefield and allow his opponent to step over him. If the winner and loser are together after the fight, the loser will be avoided, and the winner will gestures to show their obedience, to avoid another battle.

Phryne – caring parents. And watch them at this time is extremely interesting. Newborn frinyata cling Nurse abdomen for a few days after birth. Then they fade and go away from the care of his mother. “Cub” zhgutonogogo spider usually white at birth, and thus, it becomes immediately clear when friniha birth.

Very little is known about zhgutonogih spiders. There are probably only about a dozen of scientists around the world who are actively involved in the study of the features of their biology.

Recent studies in the laboratory using a high speed camera and precision equipment zvukovosprinimayuschego showed that Phryne use sound to communicate during fights males (Santer and Hebets, 2008). This is due to the vibration sensitive antennae. The enemy gets a signal through the long sensitive hairs located on the patella of walking legs.

Phryne have flat bodies, adapted for prolezaniya in cracks and other hard to reach areas where they hide in the daytime. Zhgutonogie spiders hunt at night, when they can be seen on the trunks of trees.

There were 136 species, 17 genera and 5 families of Phryne. They are found in the tropics and subtropics. Phryne hydrophilic, so almost never leave the forest, where the day hiding under crop residues, bark peeled and cracked stones. Some species are found in termite mounds. In the cave dwellers (some Phrynichus) reduced lateral eyes.

Phryne usually move sideways like crabs. With one “whiskers” they sent to the direction of motion, and the other continually feels the neighborhood.

About them a lot of rumors and tales written many European and American writers. The reason for this was very unusual, and their complete absence in temperate countries.

The males have a very interesting way to establish who among them chief. When two males encounter each other, they engage in a kind of “fighting” tournaments. They usually face pedipalps, and try to push their long front legs.
