Jumping spiders

The Life of Animals | Jumping spiders | Jumping spiders live in a variety of habitats. Euophrys omnisuperstes is a species reported to have been collected at the highest elevation, on the slopes of Mount Everest Jumping spiders have very good vision centered in their anterior median eyes (AME).  Some species (for example, Cosmophasis umbratica) are highly dimorphic in the UV spectrum, suggesting a role in sexual signaling (Lim & Li, 2005). Color discrimination has been demonstrated in Behavioral Experiments.

The principal, anterior median, eyes have high resolution (11 min. Visual angle), but the field of vision is narrow, from 2 to 5 degrees. However, the retina at the back of the tube-shaped anterior median eye to inspect objects can move off the direct axis of vision. Jumping spiders are Generally diurnal, active hunters. This enables the spiders to jump without having large muscular legs like a Grasshopper. Most jumping spiders can jump several times the length of Their body. Like many other spiders That Practically continuous leave a silk trail, jumping spiders impregnate the silk line with pheromones play a role in That social and reproductive communication, and possibly in navigation.

Certain species of jumping spiders ave been shown by experiment to be capable of learning, recognizing and remembering colors, and of adapting accordingly behviour Their hunting. Their umping spiders use vision in complex visual courtship displays. Often males are quite different in appearance from Females, and may have plumose hairs, colored or Iridescent hairs, front leg fringes, structures on other legs, and other, Often bizarre, modifications.

The male will then his front legs extend towards the female to touch her. Remains if the receptive female, the male will climb on the female's back and inseminate her with his palps. A 2008 study of the species in Current Biology Phintella vittatain female spiders Suggests That React to the male reflecting ultraviolet B light before mating, a finding That challenges the assumption held Previously That animals did not register ultraviolet B light. In recent years it has been Discovered That many jumping spiders may have auditory signals as well, with amplified sounds produced by the males sounding like buzzes or drum rolls
