Readers learn about all of the "winter whales" and the latest findings from whale research. The killer whale is one of the main characters in the book and belongs to the top of the ocean's food chain.
Most killer whales are found in Antarctica, but there are also around 3,000 in the Norwegian Sea and Barents Sea.
Killer whales are social animals that travel in pods and live in polygamous relationships: The male mates with multiple females. A pod can consist of anywhere between 4 and 40 whales and can stay together for several generations.
Killer whales are known for their intelligence, which is particularly evident in the way they communicate.
