Isolated on the Galapagos, they' ve been here so long. They' ve become a separate species. When the surf' s up, the sea lions spend hours just messing around in the waves. Surfing burns a lot of energy, and they can only do it, because these cold seas support vast numbers of fish. The sea lions share these nutrientrich waters with another equatorial misfit. Penguinsthe only penguins found in the tropics. Like the sea lions, Galapagos penguins can survive here, because the water keeps them cool and well fed. But these conditions are not constant. In El Nino years, when currents reverse, warm waters replace cold, fish populations crash and then, stuck on Galapagos, penguins and sea lions starve. |
