This jumping Spider has nearly finished off its lunch, another, smaller spider. This can be seen by the fact that the other other spiders exoskeleton is nearly translucent from the injection and ingestion of the digestive juices from the jumping spider. Jumping spiders, Family: salticidae, are the largest family of spiders with more than 500 genera and approximately 5,000 species, about 13% of all species. .Morphology: Jumping spiders are easily recognized by their eye pattern. All jumping spiders have four pairs of eyes; two very large anterior medial eyes two anterior lateral eyes, posterior lateral and medial eyes, with the eyes arranged in three rows with the exception of species. They have both book lungs and the tracheal system for breathing, known as bimodal breathing. They have an incredible internal hydraulic system which extends their limbs by altering the pressure of their body fluid (hemolymph). This enables them to jump without anatomically large legs like the hindlegs of a grasshopper.. Jumping spiders are active daylight predators unlike more sedentary spider species which spin webs and can be considered passive hunters. Using their very acute vision, jumping spiders hunt like cats, stalking prey and using ground cover as camoflage and concealment. They use their silk as a dragline for protection against falling. They are considered to be beneficials rather than pests...This jumping spider was found on the ridge above Embudo Canyon in the Sandia Mountains, east of Albuquerque, New Mexico at an approximate elevation of 8,000 ft. This is not unusual as one species of jumping spider was reported to have been collected on the slopes of Mount Everest!
