Non-vocal communication is not as common in pinnipeds as in cetaceans. Nevertheless, when they feel threatened, hauled-out harbor seals and Baikal seals may slap themselves with their flippers to create a warning sound. Teeth chattering, hisses and exhalations are also made as aggressive warnings by pinnipeds.
While their hind limbs are unfit for locomotion on land, elephant seals use their fins as support to propel their bodies. They are able to propel themselves quickly (as fast as 8 km/h (5.0 mph)) in this way for short-distance travel, to return to water, to catch up with a female, or to chase an intruder.
Baikal seals can dive up to depths of 400 m (1,300 ft) [4] and stay underwater for more than 40 minutes. [1] Most dives last less than 10 minutes and generally only 2–4 minutes. [1] Baikal seals have two litres more blood than any other seal of their size and can stay underwater for up to 70 minutes if they are frightened or need to escape ...
In the wild, mother seals only care for their pups for about four to six weeks before they are left to fend for themselves, but in that time, they learn a lot about seal behavior and especially ...
Since drag increases with speed, the work required to swim unit distance is greater at higher speeds, but the work needed to jump unit distance is independent of speed. Seals propel themselves through the water with their caudal tail, while sea lions create thrust solely with their pectoral flippers. [19]
To fully explain why beavers slap their tails we need to look at their social structures. They live in colonies of around 8 to 12 individuals and form strong family bonds.

Seal pups are born with a white lanugo (fur coat) that is shed about a month after birth. These pups do not enter the water until their lanugo is completely gone because their layer of blubber, and protection from cold ocean temperatures, remains undeveloped until shedding. Young ribbon seals were over hunted because of their soft and dense fur ...
