Scorpion Scor"pi*on, n. [F., fr. L. scorpio, scorpius, Gr. ?, perhaps akin to E. sharp.] 1. (Zo["o]l.) Any one of numerous species of pulmonate arachnids of the order {Scorpiones}, having a suctorial mouth, large claw-bearing palpi, and a caudal sting. [1913 Webster]

The venom causes great pain, but is unattended either with redness or swelling, except in the axillary or inguinal glands, when an extremity is affected. It is seldom if ever destructive of life. Scorpions are found widely dispersed in the warm climates of both the Old and New Worlds. [1913 Webster]
