Liv·er, n.  Anat. A very large glandular and vascular organ in the visceral cavity of all vertebrates.
 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 cæcal tubes, and differs materially, in form and function, from that of vertebrates.

 Liver shark Zool., a very large shark (Cetorhinus maximus), inhabiting the northern coasts both of Europe 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.
 Liver spots, yellowish brown patches on the skin, or spots of chloasma.
 Shark n.
 1. 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.
