Jumping spider. Color enhanced scanning electron microscope (SEM) image of a jumping spider (Myrmarachne formicaria). Jumping spiders stalk their prey before leaping on it from a few centimeters away. Spiders of the Myrmarachne genus look very similar to, and mimic, ants. Four eyes are seen on its head. The large chelicerae (at lower center) are pincers that are used to tear up its food. Either side of these are the two palps, sensory structures for feeling and manipulation. This is a male spider which has larger fangs. Magnification: x34 when printed 10 cm wide.
