The most common native mammal you will see in the Archipielago of Galapagos is the Galapagos sea lion, a subspecies of the Californian sea lion, which inhabits most islands. There are an estimated 50,000 individuals in the Galapagos Islands. 

If there is one activity that every visitor to the Galapagos wants to experience, it is to snorkel with the Galapagos Sea Lion.
