from The Collaborative International Dictionary of English v.0.48
Shark \Shark\ (sh[aum]rk), 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. (Zool.) 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} 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.
         [1913 Webster]

   Note: The original 1913 Webster also mentioned a "smaller
         blue shark ({C. caudatus})", but this species could not
         be found mentioned on the Web (August 2002). The
