The jumping spider is from the family Salticidae, in the order Araneae, and in the class of Arachnida. The name jumping spider? really refers to most any group of hunting spiders that have the ability to jump or leap anywhere from 10 all the way to 40 times their own body length. Depending the specie, the spider will either jump or walk. There are around 4,000 described species for the jumping spider alone making it the largest of all other spider species. More than 300 of those species are found in the United States and about 75 species are found in Europe.
The jumping spider averages at about 2 cm in length; the female spider is typically larger than the male. The jumping spider is also well known for its appearance and because of it they are easily spotted. Jumping spiders are typically brightly colored, have very outstanding patterns, and are also hairy and sometimes stocky. All together the jumping spider has four pair of eyes, two of which give it extremely sharp vision; so sharp that it actually allows it to see better than almost any animal the same size. All of the jumping spider’s eyes allow it to have a 360-degree eyesight, and on top of that the jumping spider also has the ability to turn its breast around 45 degrees.
The jumping spider is typically found in tropic regions. The tropic regions that they are found in are very different, anywhere from the rain forest to the Himalayas. The jumping spider can be found anywhere in these climates, if its day the spider can be found on the ground, on rocks, in the grass, or on trees. At night or if it is raining, the jumping spider will hide under rocks or a small web.
Because of the jumping spider’s good eyesight, their prey can be noticed anywhere from 30 to 40 cm away. At this point, the jumping spider actually scans their prey; in fact their eyesight is similar to that of a zoom lens on a camera. When the prey is registered as eatable, the jumping spider will move closer. The jumping spider even catches prey much bigger than its own size. The jumping spider does not use webs to catch its prey, but they do attach a line of silk to their prey in case they happen to fall. When the jumping spider is within good distance of their prey they will actually jump or pounce on it.
Jumping Spider Bite
The jumping spider is often mistaken for being dangerous, but in reality they are not. The jumping spider is not poisonous to humans. Like a wolf spider, the jumping spider typically does not attack humans unless they feel threatened or in danger. The only way a jumping spider bite may be hazardous is if the person bitten is allergic to spider venom, and because of that it is extremely important to consult medical attention when bitten by a spider, especially if the spider is unidentified.
