As we took the panga to the beach on Bartolome, we spotted a Galapagos Penguin sitting on the rocks. Later, the people who snorkeled near Pinnacle Rock spotted another three penguins. The small 30cm high Galapagos Penguins are unable to fly, but they use their wings and feet to swim speedily underwater, where they catch fish to eat. The cold Humboldt Current, sweeping up from the Antarctic, makes the Galapagos Islands habitable for the Galapagos penguin species. No other species of penguin can survive so close to the Equator.
