    Tailless Whipscorpion - (Phyrnus spp.)

    Creepy looking Tailless Whipscorpions are not spiders, nor scorpions. They're in a family all their own.

    Staff Writer (2/6/2014): Large, menacing pedipalps (claws) are meant to capture and crush prey as well as to aid in grooming. Though they have fangs, they cannot eat solids so they tear their prey into small pieces, sucking the fluids off of them. The forelegs (first pair in front) end in antennae and they are whipped around and in front of the Tailless Whipscorpion as it moves, feeling for nearby prey.

    Females carry their eggs for a short period of time under their belly. Once the eggs hatch, the young Tailless Whipscorpions will ride on the mother's back for almost a week before venturing off on their own.

    Usually hidden all day in dark areas, they emerge at dusk to begin hunting. If you expose one by lifting the stone it is hiding under, it will run sideways, like a crab, to escape and seek shelter elsewhere.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
