Galápagos Sea Lion, Rabida Island, Galápagos Islands, EcuadorA Galápagos sea lion floats through the clear waters of Rabida Island in the Galápagos. I like that you can see the tail on this one. Each afternoon of our Galápagos trip we had the opportunity to snorkel with sea lions. They rarely disappointed.
