English → English (gcide) Definition: Nurse shark Shark \Shark\, n. [Of uncertain origin; perhaps through OF. fr. carcharus a kind of dogfish, Gr. karchari`as, so called from its sharp teeth, fr. ka`rcharos having sharp or jagged teeth; or perhaps named from its rapacity (cf. Shark, v. t. & i.); cf. Corn. scarceas.] 1. (Zo["o]l.) Any one of numerous species of elasmobranch fishes of the order Plagiostomi, found in all seas. [1913 Webster] Note: Some sharks, as the basking shark and the whale shark, grow to an enormous size, the former becoming forty feet or more, and the latter sixty feet or more, in length. Most of them are harmless to man, but some are exceedingly voracious. The man-eating sharks mostly belong to the genera Carcharhinus, Carcharodon, and related genera. They have several rows of large sharp teeth with serrated edges, as the great white shark (Carcharodon carcharias or Carcharodon Rondeleti) of tropical seas, and the great blue shark (Carcharhinus glaucus) of all tropical and temperate seas. The former sometimes becomes thirty-six feet long, and is the most voracious and dangerous species known. The rare man-eating shark of the United States coast (Charcarodon Atwoodi) is thought by some to be a variety, or the young, of C. carcharias. The dusky shark (Carcharhinus obscurus), and the smaller blue shark (C. caudatus), both common species on the coast of the United States, are of moderate size and not dangerous. They feed on shellfish and bottom fishes. [1913 Webster] 2. A rapacious, artful person; a sharper. [Colloq.] [1913 Webster] 3. Trickery; fraud; petty rapine; as, to live upon the shark.
