Foot Of Jumping Spider, Sem

Foot of jumping spider. Coloured scanning electron micrograph (SEM) of the tip of the leg of a jumping spider (family Salticidae). In contrast to the 3-clawed foot of web-building spiders, this spider's foot has 2 claws and a pad of tufted hair (scopula, lower centre) that allows it to stick to a wide variety of surfaces. Jumping spiders use their excellent vision and jumping ability to hunt insects or spiders. Their jumping mechanism is not powered by their leg muscles; instead, muscle contraction in the front of their body causes the legs to extend by hydraulic pressure. Some jumping spiders mimic other species such as ants or beetles. Magnification unknown.
