Galapagos Wildlife
A Species Guide for Every Traveler
The Galápagos Islands are home to over 9,000 documented species. Of these, 80% of land birds, 97% of reptiles, and 20% of marine species are endemic, meaning they are found nowhere else on Earth. Due to evolving for millennia without terrestrial predators, the archipelago's famous sea lions, giant tortoises, and blue-footed boobies show absolutely no fear of humans.

Mammals
~17,000 – 24,000 Galápagos sea lions | Whale sharks at Darwin & Wolf: June–November
Galapagos sea lions and fur seals are the two native seal species. Bottlenose and common dolphins often accompany cruise ships. From June to November, whale sharks gather at Darwin and Wolf Islands for the archipelago’s largest marine wildlife spectacle.
Marine Life
2,900 marine species | Snorkeling from day 1 | Best: Darwin & Wolf for sharks
The cold Humboldt Current and warm Panama Current converge at the Galápagos, creating nutrient-rich water supporting 2,900 marine species. While snorkeling, you can easily spot manta rays, hammerhead sharks, green sea turtles, and the Galápagos penguin.
Birds
58 species | 28 endemic | Best seen: North Seymour, Española, Genovesa
The waved albatross (4 m wingspan, only nests on Española) and the blue-footed booby (mating dance performed year-round) are the most sought-after species. The flightless cormorant — the world’s only cormorant that cannot fly — lives only on Isabela and Fernandina. See also land birds
Reptiles
7 iguana species | 13 tortoise subspecies | Best seen: Santa Cruz, Isabela, Fernandina
Marine iguanas are the world’s only sea-going lizard — found on every island. The giant tortoise lives over 170 years; approximately 20,000 remain across 13 subspecies, each island-specific.
Mammals
~50,000 Galápagos sea lions | Whale sharks at Darwin & Wolf: June–November
Galapagos sea lions and fur seals are the two resident pinnipeds. Bottlenose and common dolphins regularly escort cruise ships. Whale sharks aggregate at Darwin and Wolf Islands from June to November — the single largest marine wildlife event in the archipelago.
