  phocidae   (Site not responding. Last check: 2007-10-21)
The true seals or earless seals are one of the two main groups of mammals within the seal suborder, Pinnipedia.
This combination of fasting with lactation is one of the most unusual and extraordinary behaviors displayed by the Phocidae, because it requires the mother seal to provide large amounts of energy to her pup at a time when she herself is taking in no food (and often, no water) to replenish her stores.
Because they must continue to burn fat reserves to supply their own metabolic needs while they are feeding their pups, phocid seals have developed an extremely thick, fat-rich milk that allows them to provide their pups with a large amount of energy in as small a period of time as possible.

 World Almanac for Kids
The various forms, known also as fur seals, hair seals, elephant seals, sea lions, and leopard seals, are widely distributed throughout the marine regions of the frigid and temperate zones; only the monk seals of the genus Monachus are tropical.
All three families represent a reversion to aquatic habitat from ancestral land dwellers; they have become almost perfectly adapted to life in the water, and resort to shores or ice floes only to breed and to rear their young.
The 19 species of Phocidae, or true seals, lack external ears and have shorter, relatively inflexible necks and undeveloped forelimbs; the forelimbs, however, do bear claws used for crawling up rocks and ice floes.

 Comparative Mammalian Brain Collections: PINNEPEDIA
All pinnipeds had to modify the basic mammalian pattern, which is designed for life on land, into a body form adapted to life in the three dimensional environment of water.
There are three generally recognized families in the Pinnipedia: Phocidae (true seals), Otariidae (eared seals), and Odobenidae (walruses).
Pinnipeds also spend considerable time on land along the arctic and subarctic shores of all the world's oceans (in contrast to the cetaceans and sirenians, which are completely aquatic).

There are the Phocidae that means “true seals”, the Otariidae which means “eared seals” and which includes the fur seals and sea lions, and last, the Odobenidae which means “the walrus”.
However, the most noticeable ways are that the Otariidae seals have outer ear flaps and they usually walk on both their hind and fore flippers.
On the other hand, Phocidae seals do not have visible ear flaps and they do not drag themselves along the land by their fore flippers or bodies or even use their hind flippers to drag themselves through the water.

The pinnipeds are divided into three families: the Otariidae or eared seals, the Odobenidae or walruses, and the Phocidae or earless seals.
The Otariidae and Odobenidae were long believed to have developed from bear-like ancestors, while the Phocidae were believed to have developed from members of the mustelid family, which includes weasels, badgers, skunks, and otters.
The Phocidae, or earless seals, first appeared in European waters in the late Oligocene Epoch (36 to 22.5 million years ago).

 seal --  Encyclopædia Britannica
There are two types of seals: the earless, or true, seals (family Phocidae); and the eared seals (family Otariidae), which comprise the sea lions and fur seals.
The harbour seal is whitish or grayish at birth and as an adult is generally gray with fl spots.
The adult male may attain a length and weight of about 1.8 m (6 feet) and 130 kg (290 pounds); the female is somewhat smaller.

Pinnipedia is the order of mammals that includes the seals and sea lions.

Pinnipeds are the seals (Family Phocidae), sea lions (Family Otariidae) and walruses (Family Odobenidae).
The seals group and the sea lion group is common all over the world in many habitats while the walrus group is only found in the north polar area (the Arctic).
There is a group of sea lions that are common called "fur seals." These fur seals are not true seals at all because they have external ear flaps (pinna), webbed front flippers, and can rotate their hind limbs forward.

Since they are mammals, they must always come up to the surface to breathe, although they can often hold their breath for surprising lengths of time.
The Phocidae, or true seals, lack external ear flaps and do not use their flippers to "walk" on land.
Togiak Refuge is home to five species from this group; the harbor seal and spotted seal are seen fairly frequently, while the ringed seal (Pusa hispida), ribbon seal (Histriophoca fasciata) and bearded seal (Erignathus barbatus) are less common.

 The Pinnipeds   (Site not responding. Last check: 2007-10-21)
The term pinniped, or `fin` or `feather footed`, is used to describe a group of amphibious, mammalian, aquatic carnivores that all share similarities in body shape, ecology and behaviour.
At present there are 33 known species of pinniped, 18 phocid, 14 otariid and 1 odobenid, a thirty fourth, The Caribbean Monk Seal (phocid), is sadly thought to be extinct.
The second, diphyletic view, is that phocids and otariids originated independently of each other some 20 million years ago, the otariidae and odobenidae evolving from a bear like ancestor and the phocidae from Otter like animals in the mid Miocene.

They are also called the earless seals because they lack external ears, having only a tiny, wrinkled ear opening on each side of the head.
The true seals, family Phocidae, are classified with the eared seals (sea lions and fur seals), family Otariidae, and the walruses, family Odobenidae, in the Pinnipedia--the pinnipeds are regarded as either a suborder of the order Carnivora or a separate order.
The true seals comprise 18 living species grouped into 13 genera; 10 extinct genera are also known.

Phylogenetic relationships of the Phocidae and population genetics of ice breeding seals
Due to their evolutionary origins among the terrestrial carnivores, the distribution of all pennipeds (seals, sea lions, and walrus) is essentially coastal or associated with ice in high latitudes.
In contrast, many ice breeding species direct observation of movement and dispersasl is not feasible due to the relative inaccessibility of their habitat.

 Lioncrusher's Domain -- Order Carnivora
Some sources add in the three families of Pinnipeds: Otariidae (eared seals), Odobenidae (walrus), and Phocidae (earless seals), while other sources give them their own suborder, Pinnepedia, and still other sources give them their own order altogether.
However, many authorities believe that the pinnipeds are morphologically similar to the Canoidea, and believe that the Otariidae and Odobenidae families arose from bear-like ancestors, and the Phocidae family arose from the common ancestor of the otters.
It seems there is not enough evidence in either direction, so it is up to the individual taxonomist.
