Ecological Profile

Ecosystem Structure & Biodiversity

Located 1,000 km off the Ecuadorian coast at the confluence of three major ocean currents (Humboldt, Cromwell, Panama), the Galápagos hosts extraordinary evolutionary endemism where tropical reptiles and polar penguins coexist.

Key Wildlife Facts:
  • ✓Over 80% of land birds and 97% of reptiles in the Galápagos are found nowhere else on Earth.
  • ✓Galápagos animals have no instinctive fear of humans due to evolving without large mammalian land predators.
  • ✓Charles Darwin's 1835 voyage aboard the HMS Beagle here laid the foundations for the theory of natural selection.
