noun

Shark n.

(Zool.) Any one of numerous species of elasmobranch fishes of the order Plagiostomi, found in all seas. 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 syn. Prionace glauca) 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 (Carcharodon Atwoodi) is thought by some to be a variety, or the young, of Carcharodon carcharias. The dusky shark (Carcharhinus obscurus) is a common species on the coast of the United States of moderate size and not dangerous. It feeds on shellfish and bottom fishes.
