Scopulae

Scopulae, or scopula pads, are dense tufts of hair at the end of a spiders's legs. They are found mostly on hunting spiders, especially tarantulas. Scopulae consist of microscopic hairs, each covered in even smaller hairs called setules or "end feet". The result is a massive surface area.
When the scopulae are splayed out and placed against a surface, remarkable adhesion is produced due to the accumulation of adhesion of each individual setule interacting with a substrate. The adhesion may be due to the excretion of liquid from adhesive pads, although setae can adhere in both dry and wet modes.〔Peattie, A. Dirks, J. Henriques, S. and W. Federle. 2011. Arachnids secrete a fluid over their adhesive pads. PLoSOne 6(5): e20485.〕 This enables spiders with scopulae to climb even sheer, smooth surfaces such as glass. The adhesion is so great that the spider could grip using this force and support 170 times its own weight.
Scopulae are found in addition to, not instead of, the claws at the end of each appendage, called tarsal claws.
