The northern bottlenose was hunted heavily by Norway and Britain in the 19th and early 20th centuries. It is one of the deepest diving mammals known, reaching depths of 1453 m.

The common minke whale or northern minke whale (Balaenoptera acutorostrata) is a species of minke whale within the suborder of baleen whales. It is the smallest member of the rorquals and the second smallest species of baleen whale.

The sei whale (Balaenoptera borealis) is a baleen whale, the third-largest rorqual after the blue whale and the fin whale. It inhabits most oceans and adjoining seas, and prefers deep offshore waters. It avoids polar and tropical waters and semienclosed bodies of water. The sei whale migrates annually from cool and subpolar waters in summer to winter in temperate and subtropical waters.
