Editor's note: They zip through the water at up to 30 mph, using their sensitive whiskers to help them detect prey when visibility isn’t great. They split their time between land and sea, walking on their flippers or even running if needed. And they take the prize for freediving, holding their breath for up to twenty minutes. With huge eyes and tiny ears, these fun marine mammals are beyond adorable, so make some space on your screens for a few cool Sea Lion wallpapers!
