Over the course of their 70-year lifespan, sperm whales will easily travel the circumference of the Earth in search of food and the need to breed and find a mate. Males will travel as far north as the Bering Sea and as far south as Antarctica in order to find enough food to sustain their ways of live-up to 700 squid a day! Along the way, these massive beasts battle 30-feet-long giant squids, and each other, to sustain their ways of life. National Geographic supports K-12 educators with ELA Common Core Resources.
