How fast can sea lions swim?
California sea lions are very fast swimmers, reaching speeds of 25 miles per hour in the ocean.
As members of the otariid or “walking seal” family, sea lions have large front flippers that carry a lot of strength. In the water, they swim by using their front flippers like powerful oars. They are sometimes seen porpoising, or jumping out of the water, presumably to speed up their swimming. These animals can also move quickly on land as they can bring all four flippers underneath their bodies to walk or even run on them.
What is the difference between California sea lions and Steller sea lions?
While Steller sea lions and California sea lions are similar in appearance, there are distinct ways to tell them apart like size and color.
Steller sea lions are much larger and lighter in color than California sea lions. Adult male California sea lions weigh up to 850 pounds and females up to 250 pounds. Adult male Steller sea lions weigh almost 2,500 pounds and females weigh 1,000 pounds.
How do sea lions communicate?
Sea lions primarily communicate with each other though vocalizations, including barks, growls and grunts.
California sea lions are a very social species and are known for their noisy barking. During breeding season, male sea lions may bark to establish and defend territories. Female sea lions also use a specific vocalization to communicate with their pups. In fact, mothers and pups recognize each other on crowded rookeries, or breeding beaches, through their distinct vocalizations and smells.
