Light micrograph of the tip of one of the walking legs of an unidentified species of spider, showing one of the claws which allow the spider to walk on vertical surfaces. Hunting spiders bear two claws on each walking leg whereas the weavers are provided with a third, median claw. The claws can be moved by the action of muscles and bear a comb- like row of small, ventral teeth. Magnification: x60 at 6x4.5cm size.
