The pygmy sperm whale (Kogia breviceps) is one of three species of toothed whale in the sperm whale family. They are not often sighted at sea, and most of what is known about them comes from the examination of stranded specimens. Pygmy sperm whales are found throughout the tropical and temperate waters of the Atlantic, Pacific, and Indian Oceans.

The long-finned pilot whale (Globicephala melas) is a large species of oceanic dolphin. Long-finned pilot whales are known as such because of their unusually long pectoral fins. Long-finned pilot whales are found in the North Atlantic (subspecies Globicephala melas melas), as well as the Southern Hemisphere (subspecies Globicephala melas edwardii).
