The Galápagos Sea Lion at a glance

The Galápagos sea lion is one of the most charismatic and playful marine mammals in the world. Endemic to the Galápagos Islands, these curious pinnipeds are famous for their bold, puppy-like interactions with snorkellers and divers. Juveniles in particular are endlessly playful, blowing bubbles, spinning, and mimicking divers' movements. Adults bask on beaches, boat docks, and park benches throughout the archipelago, seemingly unfazed by human presence — a testament to the islands' unique lack of natural land predators.

Diving Tips

Galápagos sea lions are incredibly curious and will often approach divers and snorkellers on their own. Let them come to you — never chase or grab them. Juveniles are the most playful and may spend extended time mimicking your movements. Bull males can be territorial, especially during breeding season — give large males space and watch for aggressive posturing.
