Large spines on whip spiders’ grasping pedipalps let them seize, impale and immobilize prey such as cave crickets.
Two elongated front legs act as whip-like sensory organs, helping the animals feel out prey in darkness because their eyesight is poor.
George McGavin described one tactic in caves: the predator reaches behind a cricket, tickles it, and triggers a jump straight into its jaws.
Whip spiders are neither true spiders nor scorpions; they belong to the separate order Amblypygi, lack silk and venom fangs, and live mainly in warm, humid tropical and subtropical habitats.
