Rhincodon typus
(gcide) | 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

(gcide) | Liver \Liv"er\, n. [AS. lifer; akin to D. liver, G. leber, OHG.
lebara, Icel. lifr, Sw. lefver, and perh. to Gr. ? fat, E.
live, v.] (Anat.)
A very large glandular and vascular organ in the visceral
cavity of all vertebrates.
[1913 Webster]
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 c[ae]cal 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.
