Seals are typically sleek-bodied and barrel-shaped. Their
bodies are well adapted to the aquatic habitat where they
spend most of their lives. Their limbs consist of short, wide,
flat flippers.
Sea lions are any of seven species in seven genera of modern
pinnipeds including one extinct species. Sea lions are characterized
by the presence of external ear. Their range extends from
the subarctic to tropical waters of the global ocean in both
the northern and southern hemispheres with the notable exception
of the Atlantic Ocean.
