With the largest brain of all animals on Earth, they are also our planet’s largest predator. Sperm whales were portrayed as monsters for centuries, but researchers today are learning that these animals and their societies are far more complex than ever believed. Sperm whale families share unique dialects, parenting techniques, and other elements of culture.
