In the remote northern islands of Darwin and Wolf, science reveals a dramatic seasonal pulse beneath the waves. A new Charles Darwin Foundation study shows fish biomass triples in the cold season—driven by migrating scalloped hammerhead sharks. Discover how ocean currents shape one of Earth’s richest marine refuges.

Galápagos sharks do not all behave the same. Hammerheads form large schools, whitetip reef sharks rest on reefs, tiger sharks repeatedly return to key feeding areas, and whale sharks undertake long migrations. Understanding these different behaviors helps protect critical habitats, migration routes, and supports more effective conservation strategies for each species.

Sharks have thrived on our planet for over 400 million years. Yet overfishing has drastically reduced global shark populations, with many shark species now threatened with extinction. Our scientific work seeks to inform conservation measures, so sharks are better protected in Galapagos and the Eastern Tropical Pacific.

Discover the Charles Darwin Foundation, established in 1959 to protect the Galapagos Islands' fragile ecosystem. As the oldest and largest science and conservation organization in the archipelago, our Research Station leads efforts to preserve this unique environment through groundbreaking research and conservation milestones.
