The Wonder of Animals

Chris Packham explores the success of the most widespread of marine mammals, the dolphin. Contrary to their amiable reputation, they are, in fact, ruthless predators. They hunt using a combination of specialised anatomy and complex communication, requiring a big brain. Chris explains the inner workings of dolphin echolocation, reveals how a pod uses body movements to communicate the location of food and explores the strategies used by orcas during a hunt.
