What does a sperm whale look like?Great sperm whales are the biggest of all toothed whales, the males usually much larger than the females. They travel in pods of up to fifty, composed of one or two males and a harem. Sperm whales are easily recognized by their massive heads and prominent rounded foreheads. They have the largest brain of any creature known to have lived on Earth. Their heads also hold large quantities of a substance called spermaceti.

Where do sperm whales live?Sperm whales are divided into Northern and Southern hemisphere populations, and can be found in all oceans. Sperm whales are found in many open oceans, both in tropical and cool waters. Sperm whales live at the surface of the ocean but dive very deeply to catch the giant squid. Only males are found in Antarctic waters.
What does a sperm whale eat?Sperm whales are known to dive as deep as 3,280 feet (1,000 meters) in search of squid to eat. These giant mammals must hold their breath for up to 90 minutes on such dives. When they dive, they use sonar to search for squid, their primary food source. The spermaceti organ may also play a part in sonar reception.
