scorpion,

any arachnid of the order Scorpionida with a hollow poisonous stinger at the tip of the tail. Scorpions vary from about 1/2 in. to about 6 in. (1–15 cm) long; most are from 1 to 3 in. (2.5–7.6 cm) long. They are predominantly tropical or subtropical, but some species live in temperate regions. During the day they hide in crevices or under objects, emerging at night to feed, mostly on other arthropods. The body is composed of a prosoma (head) covered by a solid protective covering, or carapace, and a segmented opisthosoma (body) divided into a broader mesosoma and a narrower metasoma, which ends in a sting. There are six pairs of appendages located on the prosoma: short, pincerlike appendages called chelicera, which are used to tear up food for swallowing; large appendages called pedipalps, equipped with powerful pincers used to grasp prey (which is then immobilized by stinging if necessary); and four pairs of walking legs. The first segment of the opisthosoma has vestigial appendages in the form of a genital opening (operculum), and the second segment bears unique, comblike sensory appendages known as pectines. The next four opisthosomal segments each bear a pair of respiratory structures known as book lungsbook lung,
terrestrial respiratory organ characteristic of arachnids such as scorpions and primitive spiders. Each book lung consists of hollow flat plates. Air bathes the outer surface of the plates and blood circulates within them, facilitating the exchange of gases.

, which open into the body by way of a hole, or spiracle. The metasoma is carried high in the air, in preparation for a quick stinging thrust. Although scorpion stings are painful, they are not usually dangerous to humans. Exceptions are the greatly feared scorpion Androctonus australis of the Sahara Desert, whose sting causes death in 6 to 7 hr if the victim is not treated with antivenin, and several species of the genus Centruroides, found in Mexico, which have been responsible for the deaths of a number of persons, mostly children. The scorpion neurotoxin causes convulsions; death results from respiratory or cardiac failure. Complex courtship rituals precede mating. The young scorpions are born alive and are carried for a time by the mother, leaving her after the first molt. About a year is required to reach maturity. Scorpions are classified in the phylum ArthropodaArthropoda
[Gr.,=jointed feet], largest and most diverse animal phylum. The arthropods include crustaceans, insects, centipedes, millipedes, spiders, scorpions, and the extinct trilobites.

(pop culture)
Bitter enemies Spider-Man and the Scorpion share one thing in common: a dislike of J. Jonah Jameson. As shown in Stan Lee and Steve Ditko's The Amazing Spider-Man vol. 1 #19 (1964), low-rent P.I. MacDonald “Mac” Gargan is hired by Daily Bugle publisher Jameson to shadow photographer Peter Parker to discover how he gets so many photos of Spider-Man. Since Parker is Spider- Man, his spider-sense allows him to dodge Gargan's tail, leading Jameson to make another offer in issue #20: for ten grand, Gargan undergoes mutagenic treatments by scientist Farley Stillwell to transform him into the human embodiment of the spider's natural nemesis, the scorpion. With a green ribbed exoskeleton boasting glove pincers and a telepathically controlled, 6-feet-long steel tail he can whip at nearly 100 miles per hour, the Scorpion— driven mad by his transformation—becomes a menace to not only Spider-Man but to the general public as well. Once Jameson attempts to disassociate himself from the rogue he funded, the betrayed Scorpion attacks the newspaper publisher, with Spidey swinging to the rescue. Genetically conditioned to hate Spider-Man, the Scorpion has become one of the wall-crawler's most consistent foes. He equipped his tail with an energy blaster to fight Spidey and Captain America in Marvel Team-Up vol. 1 #106 (1981), and since has added other potentially lethal modifications. The Avengers and Alpha Flight have also felt the Scorpion's sting, but Gargan's sinister focus remains upon Spider-Man, even following the hero into his various television animation incarnations, and into toy stores in the form of action figures manufactured by Toy Biz. In 2005 Marvel introduced an all-new Scorpion— a teen-age girl with a shady past—as an agent of S.H.I.E.L.D. in the pages of Amazing Fantasy. Meanwhile Gargan, after a brief anti-Spider-Man alliance with the Green Goblin, became the new Venom after bonding with the alien Venom symbiote. The name “Scorpion” has been used on several occasions for other villains, including the nemesis in the film Blake of Scotland Yard (1937), Popular Publications' pulp magazine The Scorpion #1 (1939), and as a black-robed mastermind in the twelve-chapter movie serial The Adventures of Captain Marvel (1941). Atlas/Seaboard Publications produced three issues of a pulp-hero comic book titled The Scorpion in 1975.

Twenty tools that can be used to construct specialised programming environments. The Scorpion Project was started by Prof. Richard Snodgrass <rts@cs.arizona.edu> as an outgrowth of the SoftLab Project (which produced the IDL Toolkit) that he started when he was at the University of North Carolina. The Scorpion Project is directed by him at the University of Arizona and by Karen Shannon at the University of North Carolina at Chapel Hill.

Scorpion

(dreams)
Dreaming about a scorpion may be symbolic of something in your environment which is hurtful, dangerous, and “stinging.” It may represent bitter words and very negative attitudes. Superstition-based dream interpretation books say that a scorpion may constitute a warning. It further states that if the scorpion in your dream bit you, you will overcome your problems. However, if you killed the scorpion, be exceptionally careful around people who are not your friends, or are false friends. Some believe that the scorpion is a symbol of transformation.
