The adults are dark-grey with a darker stripe along,the
spine; the belly is light-coloured with pale »pots and streaks. Distributed
in the icy'rei.,:ions of the Antarctic, but is of fairly rare
occurrence. Tho genus contains a single Species, Ëoss's'seal.
Modern systematics includes 20 seal Genern,* represented by
32 species, in the order *Pinnipedia*. The large-st rababers of genera
* Belkin (1967) lists a new 33rd species,. the island seal or
antur (Phoca insularis sp. nova); W. Rice and B. ,cheffer (1968)
- also raise that form to species level as rhoca kurilonsis Junkae, 1942.
and species are found in the family Phocidae (13 genera, 18 species);
. there are•somewhat fewer in the family Otariidae (six•enera, 15 species).
The family Odobaenidae contains only one genus and one species.
All the pinnipedes in the world's oceans can be classified
according to the regions where they live into a few large geographical
groups;
pinnipedes of the North Atlantic and Arctic Oceans;
pinnipedes of the northern part of the Pacific Ocean;
seals of'inland waters (Caspian Sea, Lake Baikal, Lake .
Ladoga, etc.); and
seals of the southern hemisphere.
. That classification of pinnipedes is justifiable and is convenient
for discussing the biologY of themarine mammals that inha-.
bit the various regions of the world's•oceans.

The Jorth Atlantic and the Arctic occupy a leadinG place
among the world's oceans.with respect to the numbers of pinninede
species thnt live in them.
The pinninedes found there are mostly
members of the . rhocidae family -- hall) seal, heeded seal, •
rinGed seal, benrded seal, harbo.Ar seal, and Grey seal; another
pinnipede tnat is found there is the •nlrus.
Althous;h the number of seal species in that reGion is not
particularly high, sono of them are the princii:al quarry of sealing
oh! po nnd shore-based sealinG. That is esecially the case with the
abuidnnt species the harp
seal, yhich forms three herds (the
\Juite uea, the jan mayen, and llte i,ewfounnland herds) ae(i which is
