Scorpion

Scorpion Anatomy: As part of the arachnid class, scorpions have two main body segments and four pairs of legs. The most distinctive characteristics of the scorpion are its long, clawlike pedipalps, which look like miniature lobster claws, and their stinging tail. The tail is mainly used for defense as opposed to capturing prey.

Diminutive But Deadly: One of the smallest scorpions, the buthid, which rarely reach more than 5 inches in length, is actually one of the most lethal scorpions. One shot of venom from its stinging tail can paralyze the heart and respiratory system of its victim.

The Larger Variety: The scorpionid family includes the world's largest scorpions, which can measure up to 8-½ inches long. These larger species tend to be less venomous and use their size to overpower victims instead.

Scorpion Survivors: Scorpions are hardy survivors. Scientists have frozen them solid, only to watch them thaw out and keep on crawling. One thing scorpions can't survive without is loose soil in which to burrow.
