On an evolutionary timescale, it’s believed that the Pinnipeds split off from other carnivores (like canines and felids) around 50 million years ago. Their huge flippers, thick layers of blubber, and long whiskers enable them to survive harsh life in the cold ocean waters.

How do seals move?
Their more streamlined bodies enable them to cut swiftly through the water, while their hind flippers are angled backward to propel them forward. They move clumsily on land by crawling on their bellies and dragging themselves forward with their front flippers. Sea lions, by contrast, are generally better adapted for life on land, since their hind flippers rotate forward and function more like feet. Whereas the seals rely more on whole-body movements in the water, sea lions largely swim by rotating their hind flippers.
