Mastigoproctus giganteus

Mastigoproctus giganteus

''Mastigoproctus giganteus'', the giant whip scorpion, also called the giant vinegaroon or grampus, is a species of whip scorpions in the family Thelyphonidae.
Vinegaroon Captive specimen. Native to the southern US and Mexico, this is an arachnid also commonly known as whip scorpion.

The name 'whip scorpion' refers to their resemblance to true scorpions and possession of a whip-like tail. 'Vinegaroon' is based on their ability when attacked, to discharge an offensive liquid which contains acetic acid, producing a vinegar-like smell.

This species can grow to be 40–60 millimetres long, excluding the tail. They have six legs used for movement, two long antenniform front legs that they use to feel around for prey and detect vibrations, and two large pedipalps modified into claws that they use to crush their prey. They have a long, thin, whip-like tail, the origin of the common name whipscorpion. From the base of this tail they can spray a substance composed of 85% acetic acid in order to defend themselves. Acetic acid is the main component of vinegar, so the spray smells strongly of vinegar, leading to the common name "vinegarroon".

''Mastigoproctus giganteus'' have eight eyes: two in a pair on the front of the head and three on each side of the head. These eyes are very weak, so ''Mastigoproctus giganteus'' navigates mostly by feeling with its long front legs, tail, and pedipalps.

It lives in the southern US and in Mexico. ''Mastigoproctus giganteus'' preys on various insects, worms, and slugs.
