About the Bottlenose Dolphin

The bottlenose dolphin is a highly intelligent marine mammal found in warm and temperate seas worldwide. Sleek and grey with a short beak and a permanent 'smile', it is one of the most familiar of all cetaceans. Dolphins live in social groups called pods and cooperate to hunt fish and squid, using echolocation, bursts of clicks, to find prey in murky water. They communicate with whistles, and each dolphin develops a signature whistle that works like a name. Curious and playful, they often ride the bow waves of boats.
