Mastigoproctus giganteus (Lucas)
Orig. Comb: Thelyphonus giganteus Lucas 1835
only whipscorpion n. of Mex.
AZ-TX-OK, FL / Mex - UF, 2011
Carnivorous - preys on smaller creatures (insects, worms and slugs).
The vinegaroon is nocturnal and has poor vision. The whiplike tail is used as a sensory organ, as is the first pair of legs, which is not used for walking. Although its tail in unable to sting, this creature can spray an acidic mist from a scent gland at the base of the tail when disturbed. The spray is 85% concentrated acetic acid/vinegar, hence the common name "Vinegaroon." The heavy pinching mouthparts (modified pedipalps) can also inflict a painful bite. Although very unlikely to attack humans, it can certainly defend itself if provoked.
