Scorpions are nocturnal or diurnal, predatory animals
that feed on a variety of insects, spiders, centipedes, and
other scorpions. The larger scorpions occasionally feed on
vertebrates, such as small lizards, snakes, and mice. Prey
is detected primarily by sensing vibrations with the pectine
organs. The pedipalps have an array of fine sensory hairs
that sense air-borne vibrations; the tips of the legs have
small organs that detect vibrations in the ground. Most
scorpions are ambush predators who detect prey when it
comes within reach.
