HE ORDER AMBLYPYGI is divided into 3 families and 130 species. Also called tailless whip-scorpions, these arachnids have squat bodies, which are flat in profile, and a broad cephalothorax.

The first segment of the rounded abdomen is stalklike. Whip-spiders have eight eyes: a middle pair and three lateral pairs. The large pedipalps may be long and slender or short and stout. Spiny, sharp-tipped, and six-segmented, they seize and hold prey, while the two-segmented, fanglike chelicerae tear pieces off. The much-segmented, very long first pair of legs are used as feelers.

Whip-spiders are nocturnal, do not sting or bite, and prey on insects and other arthropods. Kggs hatch out inside a sac under the female's abdomen, and the young then climb on to her back.
