northern bottlenose whale

The northern bottlenose whale (Hyperoodon ampullatus) is a large, beaked whale found in the deep, colder waters of the northern Atlantic Ocean. These whales are greenish-brown to gray and are known for their bulbous foreheads that slope sharply to their beaks.12

Northern bottlenose whales are toothed whales and are capable of very deep dives, with one recorded to nearly 1,500 meters (4,900 feet) and remaining submerged for almost two hours. Their diet consists of squid, fish, and other bottom-dwelling animals. They typically travel in pods of 2 to 10 or more individuals and are known to stay with a disabled member, making the pod vulnerable. The oil from these whales was historically known as "Arctic sperm oil".2
