Sperm Whale Facts

A large sperm whale can contain up to 7 tons of oil, making them the most valuable targets during the whaling era.

Two whales got stranded on a sandbar at Mahia Beach in New Zealand. A mother and her calf kept beaching themselves for over an hour. Rescuers were close to giving up. Then a wild dolphin named Moko showed up. The whales seemed to answer his calls. They followed Moko through a narrow channel and swam free.
