Typically found in various aerial, terrestrial, and aquatic environments.

Range

Found in Norway.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Common Diving-Petrel

<em>Pelecanoides urinatrix</em>, the common diving petrel, is a seabird in the family Procellariidae distributed across the Southern Ocean and subantarctic regions, with records extending to Norway. This species typically inhabits open marine environments and coastal cliffs, where it nests in burrows on islands and steep shorelines. The common diving petrel is notable for its highly specialized diving behavior, using its wings to propel itself underwater in pursuit of small fish, crustaceans, and zooplankton. Its compact body, short wings, and strong feet make it well adapted to both aerial and aquatic locomotion, though flight is typically low and whirring. <em>Pelecanoides urinatrix</em> is generally nocturnal at its nesting colonies, helping to reduce predation risk. Adults typically form long-term pair bonds and raise a single chick per breeding season in underground burrows. The species is assessed as Least Concern, though some island populations have experienced pressure from introduced predators. Its ecology reflects a highly marine-adapted lifestyle across cold southern waters.
