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.
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 (/ ˈ f oʊ s ɪ d iː /). They are sometimes called crawling seals to distinguish them from the fur seals and sea lions of the family Otariidae.
Fur seals are any of nine species of pinnipeds belonging to the subfamily Arctocephalinae in the family Otariidae.They are much more closely related to sea lions than true seals, and share with them external ears (), relatively long and muscular foreflippers, and the ability to walk on all fours.

The mystacial vibrissae can be very long, and regularly extend beyond the ears. Adults have all white vibrissae, juveniles and subadults have a mixture of white and black ...
Crabeater seals can raise their heads and arch their backs while on ice, and they are able to move quickly if not subject to overheating. Crabeater seals exhibit scarring either from leopard seal attacks around the flippers or, for males, during the breeding season while fighting for mates around the throat and jaw. [3]
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 ...
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.

The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic ...
