Seals/sea lions La Jolla cove.

Here is a picture I took of the seals/sea lions in La Jolla California. I honestly don't know how to tell the difference between the two I believe the one bigger one is a sea lion and the other two smaller ones are seals. I could be wrong though. so If you know. let me know I think it's amazing how close you can get to them. It's sad though because some people don't treat them the way they should be treating a living creature.
