Habitats, lifestyle

Homeland is North, South America. The predator lives on banana plantations, but does not eat fruit at all. A huge creature does not weave a web, waits for the victim in a secluded place, hides among the leaves. The body color is similar to the bark of trees, so the predator goes unnoticed.

It does not form permanent holes; it does not create hunting networks; it quickly moves from one place to another. Thanks to these features, the animal began to be called a tramp, a nomad, a wanderer, a runner.

On a note!

During such trips, the spider often crawls into the abode of a person. Hiding among dishes, in cabinets, clothes, shoes. During the day, he quietly hides in a secluded place, with the onset of darkness he begins to become active.

Nutrition

There are no internal digestive organs, digestion of food occurs outside under the influence of predator saliva. The tramp hunts for large insects, other spiders, as well as birds, rodents, amphibians. At the time of the attack, it rises to its feet, warning of its intentions.

On a note!

At the sight of a prey, the predator immediately rushes to attack, inflicts a bite, introduces a poisonous substance. Almost instantly paralyzes the prey, injects saliva, and after a while absorbs the contents. Enzymes dissolve the insides to a liquid state. From insects there remains only a shell.

Danger to people
