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.
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]
The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. 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 ...
The vertebra (back bones) reach to the end of the tail and the rest is made up of muscles and connective fibers. It comes in very useful when the beaver is swimming.
Aquatic mammals such as seals and otters can produce sound using the larynx. Fiddler and ghost crabs can produce non-vocal noise by striking, drumming or tapping on a substrate while they are on shore, [ 8 ] while aquatic invertebrates like cleaner shrimp often produce noises by clapping their claws.

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 ...
Bearded seals reach about 2.1 to 2.7 m (6.9 to 8.9 ft) in nose-to-tail length and from 200 to 430 kg (441 to 948 lb) in weight. [5] The female seal is larger than the male, meaning that they are sexually dimorphic. Bearded seals, along with ringed seals, are a major food source for polar bears. [6]
Elephants have massive ears to help regulate their body temperature. They have huge blood vessels in their ears. The blood vessels are large and quite visible on the backs of the elephant’s ears.
