Definition: Oil shark
, 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. (Zo["o]l.) 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
related genera. They have several rows of large sharp
teeth with serrated edges, as the great white shark
or Carcharodon Rondeleti
of tropical seas, and the great blue shark
) 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 (Charcarodon Atwoodi
) is thought by some to be
a variety, or the young, of C. carcharias
. The dusky
shark (Carcharhinus obscurus
), and the smaller blue
shark (C. caudatus
), both common species on the coast
of the United States, are of moderate size and not
dangerous. They feed on shellfish and bottom fishes.

(oil), n. [OE. oile, OF. oile, F. huile, fr. L. oleum;
akin to Gr. ?. Cf. Olive
Any one of a great variety of unctuous combustible
substances, more viscous than and not miscible with water;
as, olive oil, whale oil, rock oil, etc. They are of animal,
vegetable, or mineral origin and of varied composition, and
they are variously used for food, for solvents, for
anointing, lubrication, illumination, etc. By extension, any
substance of an oily consistency; as, oil of vitriol.
Note: The mineral oils are varieties of petroleum. See
. The vegetable oils are of two classes,
(see under Essential
), and natural oils
which in general resemble the animal oils and
fats. Most of the natural oils and the animal oils and
fats consist of ethereal salts of glycerin, with a
large number of organic acids, principally stearic,
oleic, and palmitic, forming respectively stearin,
olein, and palmitin. Stearin and palmitin prevail in
the solid oils and fats, and olein in the liquid oils.
Mutton tallow, beef tallow, and lard are rich in
stearin, human fat and palm oil in palmitin, and sperm
and cod-liver oils in olein. In making soaps, the acids
leave the glycerin and unite with the soda or potash.
