Common Jumping Spider
This is a drawing of a Common Jumping spider i did yesterday, Heres some info on Jumping spiders.
Jumping spiders live in a variety of habitats. Tropical jungles harbor the most species, but they are also found in temperate forests , scrub lands, deserts, the intertidel zone (in Malaysia), even mountains (one species is reported to have been the spider collected at the highest elevation, on the slopes of Mt.Everest (Wanless, 1975).
You can usually recognize a Jumping spider by their eye pattern. They typically have eight eyes
arranged in two or three rows, the two front eyes are the biggest and most forward facing. Colors and patterns vary widely, several species mimic ants. The jumping spider has a very unique and developed internal hydraulic system that allows them to extend their limbs by altering the pressure of body fluid (blood) within them. This enables them to jump without large muscled legs like a grasshoppers. The jumping spider can therefore jump 2o to 6o or even 80 times the length of its body.
