Fin whale hunting is conducted from medium-sized boats that are exclusively used for whale hunting but are not equipped for flensing the whale nor processing and storing meat and blubber. It readily feeds on small fishes like krill, crabs, shrimp, squid, lobsters and copepods. Sounds emitted by fin whales are one of the lowest in the animal kingdom.

How is sound … Sound is such a vital component of a whale’s reality also due to how easily sound vibrations move through the water -- they travel 4X faster in water than vibrations produced in the air! How is sound used to help make long-term measurements of the ocean? The hunting grounds are within Iceland’s 200 miles exclusive economic zone (EEZ) and the whales are towed to the Icelandic land station for flensing and processing.
