North Seymour is home to one of the island’s first conservation projects. In the 1930s, the crew of Captain Alan Hancock’s ship transferred 72 land iguanas from the nearby Baltra Island to North Seymour in the hopes that the reptiles would fare better without the feral goats competing for food. At last count in 2014, there were 2500 land iguanas on the island.

North Seymour and neighbouring Mosquera Islet are home to a large population of sea lions. Snorkelling here puts you up close and personal with these curious creatures and their young pups.

Also here is a flamingo lagoon on the isolated Bachas Beach, and the largest nesting colony of great frigate birds.
