Up to 23 species of whale have been listed in the Galapagos Islands. The most frequently spotted whales include orcas (actually dolphins), blue whales, humpback whales and sperm whales. The primetime for watching dolphins is when the cold Humbolt current runs through the area, from July to November. Whales are the largest mammals on the planet, with the blue whale in position number one for the biggest species. The Galapagos whales can range from 600 pounds up to an impressive 200 tons. Galapagos Whales are famous for their unique underwater vocalizations that can last for hours and include complex combinations of howls, long moans, and cries.
Researches believe that the calls of whales can be heard for thousands of miles. *Galapagos Whales amplify vocalizations by using a glob of fat that perches on the upper jaw of the animal.
