The most commonly observed species are members of the small tooth whales, e.g. harbour porpoise (Phocoena phocoena), bottlenosed dolphin (Tursiops truncates) and white-beaked dolphin (Lagenorhynchus albirostris) (Bjorge, Skern-Mauritzen, & Rossman, 2013). Larger tooth whales in the region include the killer whale (Orcinus orca), which are commonly observed along the coast. Occasionally sperm whale (Physeter macrocephalus) are seen offshore. Tooth whales feed mainly on fish, but are also known to feed on seal, octupus and shark.
