   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.

   note: most of the venous blood from the alimentary canal
         passes through it on its way back to the heart; and it
         secretes the bile, produces glycogen, and in other ways
         changes the blood which passes through it. in man it is
         situated immediately beneath the diaphragm and mainly
         on the right side. see bile, digestive, and
         glycogen. the liver of invertebrate animals is
         usually made up of caecal tubes, and differs
         materially, in form and function, from that of
         vertebrates.

   liver shark zool., a very large shark cetorhinus

      and north america. it sometimes becomes forty feet in
      length, being one of the largest sharks known; but it has
      small simple teeth, and is not dangerous. it is captured
      for the sake of its liver, which often yields several
      barrels of oil. it has gill rakers, resembling whalebone,
      by means of which it separates small animals from the sea
      water. called also basking shark, bone shark,
      hoemother, homer, and sailfish; it is sometimes
      referred to as whale shark, but that name is more
      commonly used for the rhincodon typus, which grows even
      larger.
