There are 18 species of earless seals, including the harbor, leopard, and elephant seals. Earless seals can hold their breath for up to 90 minutes, allowing them to dive to great depths in search of food. Some earless seals can stay underwater for several hours at a time, using their slow metabolism and ability to conserve oxygen to survive.
Earless seal. The earless seals, phocids, or true seals are one of the three main groups of mammals within the seal lineage, Pinnipedia. All true seals are members of the family Phocidae (/ ˈfoʊsɪdiː /). They are sometimes called crawling seals to distinguish them from the fur seals and sea lions of the family Otariidae.
- Size and Weight: True seals range in size from the 3 feet and 100 pounds Baikal seal to the 16 feet and 7,100 pounds southern elephant seal male. The southern elephant seal male is not only the largest seal species but is also the largest member of the order Carnivora.
- Appearance: Seal appearance varies among the species. However, all species have feet-shaped fins, allowing for these species to be expert swimmers. Most species have thick layers of fat, also known as blubber, to keep the animals warm in cold oceans, in addition to dense fur.
- Diet: Seals are opportunistic carnivores, eating mainly fish while in the water.
- Habitat: All pinniped species are considered semi-aquatic marine mammals that spend some of their time at sea and the other part of their lives on land or sea ice.

Three million years old fossilized seal tooth discovered on Victorian Beach suggests that earless seals used to inhabit Australian shores. Many newborn pups die because of drowning as blocks of floating ice melt.
