Level 4: Independent reader Perfect for kids who are reading on their own with ease and are ready for more challenging vocabulary with varied sentence structures.

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.
