Fin whale

Balaenoptera physalus

Fin whales are the second largest animals in the world and the most frequently encountered baleen whale species in the Azores. Their most distinguishing feature is the asymmetrical markings on the head: on the right side the lower lip, mouth cavity, and baleen plates are white, whereas on the left these features are dark. The dorsal fin is smaller and more falcate than that of the similar-looking sei whale, and they have only one ridge on the head (unlike the Bryde’s whale which has three). Fin whales are among the fastest of the whales, reaching speeds up to 47 km/hr. Because of these fast speeds the fin whale has gained the nickname “the greyhound of the sea”. Fin whales have a wide global distribution. While many populations are thought to be migratory, resident populations also exist. In the Azores migratory fin whales are seen primarily during the spring months. They are usually encountered alone or in small groups and often follow the same path. Sometimes we can observe feeding behaviour as they pass by the Azores.
