There is also a colony of Galapagos sea lions on de la Plata Island, just offshore of mainland Ecuador. This colony was introduced to the island in 1986.

Galapagos sea lions tend to stick close to the coast. You may find them fishing and playing in the water, or sunning themselves on the rocks and beaches. If it’s a hot and sunny day, they may look for shade under vegetation or under a cliff.

The area that a colony tends to gather on land is called a “hauling-out” area.

Dominant males may show aggression against other male sea lions- if they feel the need to defend their territory and harem of females. And if you happen to be a sardine, watch out!

But the Galapagos sea lion does not feel threatened by humans, and therefore, is not aggressive toward them. In fact, they are known for being curious and playful, especially the young (which do not reach maturity until they are 4 or 5 years old).

If you ever find yourself in the Galapagos Archipelago, you may even have the privilege of swimming with the sea lions. Just remember to be respectful of their space.

And watch out where you leave your backpack, or you may find a Galapagos sea lion using it as a comfy pillow.
