Whales and Dolphins are a very distinctive and dazzling group of mammals. These magnificent animals can be found mostly in the Archipelago’s west, specifically in the Bolivar Channel between Isabela and Fernandina islands, but also to the south of the Galápagos. In Galápagos, there are two groups of Whales: The Baleen Whales and The Toothed Whales. The Baleen Whales have hair-like structures in their mouth which they use to filter food from water. Baleen whales are also known for having extremely large tongues, These aid in the movement of trapped food, aid in swallowing, and allow them to squeeze excess water from their mouths. On the other hand, Toothed Whales usually feed on larger prey such as fish and other marine mammals. They also are noticeably smaller than baleen whales, growing to around 43 feet in length (13m). The only toothed whale that grows longer than this is the Sperm Whale.
