[citation needed] Unlike other pinnipeds, the ribbon seal lacks the lobes that divide the lungs into smaller compartments. [7] The ribbon seal can grow to a length of about 1.6 m (5.2 ft) and a weight of 95 kg (209 lb), with males being larger than females. The main predators of ribbon seals include great white sharks and orcas. [8]
Freshwater seals are pinnipeds which live in freshwater bodies. The group is paraphyletic in nature, the uniting factor being the environment in which these pinnipeds live. The vast majority of all modern seals live solely in saltwater habitats though this is likely due to the rarity of sufficiently large freshwater bodies rather than the ...

The Australian scientists put LED lights in striped patterns on seal decoys to deter great white sharks. The method was found to be effective. But, there are hundreds of species of shark in ocean ...
It was first photographed by Chris Fallows and Rob Lawrence who developed the technique of towing a slow-moving seal decoy to trick the sharks to breach. [150] Between April and September, scientists may observe around 600 breaches. The seals swim on the surface and the great white sharks launch their predatory attack from the deeper water below.
A humpback whale (Megaptera novaeangliae) A leopard seal (Hydrurga leptonyx). Marine mammals are mammals that rely on marine (saltwater) ecosystems for their existence. They include animals such as cetaceans (whales, dolphins and porpoises), pinnipeds (seals, sea lions and walruses), sirenians (manatees and dugongs), sea otters and polar bears.
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.
