What is the difference between a sea lion and a seal?
The main difference between a sea lion and a seal is their morphology and behavior. Sea lions have visible external ears and powerful forelimbs that allow them to move around on land in a more agile manner. Seals, on the other hand, have internal ears and shorter front flippers that force them to move on their bellies when on land. Sea lions also have more developed teeth than seals, which allows them to eat a wider variety of prey, while seals eat mainly fish and crustaceans.
