Two mighty currents dictate the life cycle of a volcanic paradise
In short: Discover why the Galapagos Archipelago is considered a cradle of evolution. This documentary explores how two opposing ocean currents create a unique biological laboratory by alternating between cold and warm marine life every six months.
The biodiversity of the Galapagos is driven by a rhythmic inversion of ocean temperatures. For half of the year, the ice-cold Humboldt Current from Antarctica dominates, introducing species typically found only in frigid regions. During the other half of the year, the warm Panama Current takes over, bringing tropical life to the islands.
A diverse range of creatures thrives together here due to the ongoing interaction of two mighty tides, featuring deep-sea iguanas, massive tortoises possessing long necks like snakes, and albatrosses typically seen across vast seas. Located roughly 1000 km west of South America, these volcanic islands serve as a unique intersection of global marine systems.
