When comparing Seal vs See, marine mammals reveal clear differences in their bodies, habitat, flippers, movement, and natural adaptations. Marine mammals are animals that evolved from land mammals and re-entered the ocean, where they depend on water for life.
They have different shapes and sizes, including flippered sea dwellers, hybrid creatures, swimmers, divers, and grazers. The five main groups include baleen whales, toothed whales, sea cows, pinnipeds, and marine fissipeds. Seals, sea lions, and walruses are pinnipeds, a Latin term meaning fin or flipper-footed.
They spend the majority of their time in the ocean but return to the shore for long periods. Their main differences can be seen through physical characteristics, adaptations, anatomy, character traits, shape, bodies, and front fore flippers.
The first difference appears in how these animals move and use their flippers. A California Sea Lion has large fore flippers that help it walk on land and swim, while its body is usually slimmer with less fat.
An Elephant Seal, like common seals such as the Harbor Seal, has smaller fore flippers mainly used to help it swim and may wiggle its large bodies to move on land. Their face and snouts also differ:
a sea lion has a large pointed snout and slimmer face, while a seal has a compacted snout, larger head, and rounder head. Sea lions (otariids) are powerful in water and move well on land.
In Oregon, large groups of male California sea lions and Steller sea lions can be seen. These eared seals have visible ear flaps, longer fore flippers, and can fold their hind quarter beneath themselves on dry land.
Older male California sea lions develop a bony bump on the forward, top part of the head, called a sagittal crest. The crest may turn white with age, giving older males a distinguished look.
