Conclusion
Sea lions and seals are two groups of marine mammals that are often confused for one another, but they are actually quite different. While they share many similarities, there are several key differences, including their external ears, foreflipper shape, vocalizations, and distribution. By learning to identify these differences, you can easily distinguish between sea lions and seals.
