   What’s the difference between a seal and sea lion/fur seal? Seals and sea lions/fur seals differ in a number of ways, but here are four that are easy to spot. Sea lions/fur seals show external ear flaps; seals show only ear holes. Sea lions/ fur seals have long, hairless, front flippers with short nails; seals have short, fur-covered

   Think for a moment about marine mammals: seals, walruses, dugongs and whales. Seals and walruses are primarily cold-water species that eat mostly fish and can spend part of their time on land (or ice). Dugongs and manatees are tropical herbivores and are entirely aquatic.

   Suborder Pinnipedia: seals, sea lions and walruses. As a group, they are fairly young, having been around for only about 25 million years. They consist of three families: Otariidae: sea lions. Phocidae: true seals. Odobenidae: walruses. Otariidae (sea lions) have: small, but obvious external ears. long, flexible necks.

   What is the difference between a sea lion and a seal?

   • Sea lions have ear flaps and flippers that rotate forward, whereas seals lack ear flaps and cannot rotate their flippers (and thus have reduced mobility on land compared to sea lions). 5b. Use the dichotomous key for pinnipeds to identify each species. Species 6 is a Steller sea lion.

   How do you identify marine mammals?

   • To identify the marine mammals, students should use the dichotomous keys provided: one for cetaceans (whales, dolphins and porpoises) and one for pinnipeds (seals, sea lions and walruses). A dichotomous key is a systematic guide to species identification. First, students should read the two options under number one.

   How do seals and sea lions get around?

   • On land, seals and sea lions also have different methods for getting around. Sea lions, fur seals, and walruses are able to rotate their rear flippers up and under their bodies so that they can waddle on all four flippers. This enables their agile movement and balance on land. Seals, however, cannot do this and instead shimmy on their bellies.

   Are seals good swimmers?

   • Seals, too, have key adaptations that make them efficient swimmers, like lots of blubber to make them buoyant. When at sea, northern elephant seals spend 85 to 95 percent of that time underwater and make massive migrations up to 13,000 miles long. Diving is part of life for pinnipeds, and even for sea creatures they are impressive divers.

   Do harbour seals eat sea ice?

   • ]. Throughout most of their range, harbour seals are not typically associated with sea ice. They even tend to avoid ]. As such, decreasing sea ice may increase the available habitat for wards range expansion. However, other features, such as bathymetry, may still limit their foraging sites during the winter like on Svalbard.

   Are pinnipeds marine mammals?

   • Flippered and charismatic, pinnipeds (which includes seals, sea lions, and walruses) are true personalities of the sea. Like whales, manatees, and sea otters, they are marine mammals, meaning millions of years ago their ancestors evolved from a life on land to a life at sea. Today, they remain creatures of both land and sea.

   In general, marine mammals are larger than mammals on land, an adaptation that minimizes the area of skin in contact with the water. Elephant seals and Walruses can weigh up to 4 tons, and even the smallest seals are notably rotund.
