Sea Lions have a wide distribution out there in the world. This is why people tend to think that there are so many of them out there. The majority of them live in the sub Arctic areas where it extremely cold. Others prefer to live in the warmer waters of the tropics. It is important to note that their aren’t any Sea Lions that live in the Atlantic Ocean but they do have their habitat in all the other oceans in the world.
What you will find is that the habitat and distribution of Sea Lions really depends on the species that you identify. The Southern Sea Lions are found in South America. They can be found all the way down to Rio de Janeiro and on the other end into Peru. The California Sea Lions are of course found there, all along the coast. They even extend into the Western portion of Mexico. They have also been found living in the Southern region of Isla Tres Marias.
Since Steller Sea Lions prefer the colder weather they reside mainly in the sub Arctic part of the Pacific Ocean towards the North. They also live on the ice and in the waters of the Bering Sea and the Okhotsk Sea. One species lived in Japan, but today is extinct.
