[24] California sea lions sometimes follow dolphins and exploit their hunting efforts. [4]
The largest of the eared seals, Steller sea lions are quick swimmers, about as fast as the smaller California sea lions. Glide velocity of individual Steller sea lions has been measured as 2.9–3.4 meters or 1.2–1.5 body lengths per second, which is close to the optimal swim velocity of 1.4 body lengths per second based on the minimum cost ...
In addition, seal lions have large, elongated fore flippers compared to seals’ comparatively petite front feet. Sea lions are also noisy and can bark loudly. “Seals are quieter, vocalizing via ...
