Scientists refer to this motion as a “clap.”. Sea lions are the only aquatic mammals that swim this way. Seals, walruses, whales, otters, and others rely on the back end of their bodies—their tail—to produce thrust. Instead, the sea lion tail is used like a rudder.
May 24, 2024 · Any seals left in the North Pacific, namely the walruses, suffered the worst. Whilst this latest study can’t yet give a definitive answer on where seals originated, it has created the first unified evolutionary tree for all extinct and living pinniped species.
May 6, 2021 · Even though all seals and sea lions are descended from a common ancestor, they use two radically different modes of propulsion: true seals (phocids) swim with their feet; fur seals and sea...

Scientific Name: Pinnipedia. Diet: Carnivore. Average Life Span In The Wild: Up to 30 years. Size: 3 feet to 20 feet long. Weight: 100 pounds to 4.4 tons. There are 33 species of pinnipeds alive...
May 16, 2017 · Whales, dolphins, and seals all follow the same evolutionary patterns. From the poles to the equator, marine mammals such as seals, dolphins, and whales, play an important role in global ecosystems as apex predators, ecosystem engineers, and even organic ocean fertilisers.
Seals can be found in a variety of ocean habitats. The largest concentrations of seals are found in California and New England.

Seals are pinnipeds, a group of animals with three separate families—phocidae (eared seals), otaridae (non-eared seals), and odobenidae (walruses)—that are the only mammals that feed in the water and breed on land. Where do they come from? Evidence suggests that pinnipeds evolved from a bear-like land animal that hunted in the water for food.
