September 2000 LONG-FINNED PILOT WHALE (Globicephala melas): Western North Atlantic Stock
There are two species of pilot whales in the Western Atlantic — the Atlantic or long-finned pilot whale, Globicephala melas, and the sh ort-finned pilot whale, G. macrorhynchus. These species are difficult to identify to the species level at sea; therefore, some of the descriptive material below ref...
