The Galápagos Sea Lion (Zalophus wollebaeki) is a marine mammal found only in the Galápagos Islands, making it an endemic species unique to this remarkable archipelago. Known for its intelligence, curiosity, and outstanding swimming abilities, the Galápagos Sea Lion is one of the most beloved animals visitors encounter during trips to the islands.

Although it lives near the equator, the surrounding waters are cooled and enriched by the Humboldt Current and the Cromwell Current, creating an environment rich in fish and other marine life. Large colonies of Galápagos Sea Lions can often be seen resting on sandy beaches, rocky shores, and coastal islands.
