Wild dolphins are highly intelligent marine mammals that belong to the family Delphinidae. They are known for their playful behavior and social structures, often living in groups called pods. These pods can range from a few individuals to over a hundred, depending on the species and environmental conditions. Dolphins communicate using a variety of sounds, including clicks and whistles, which help them coordinate hunting and maintain social bonds. They primarily inhabit warm and temperate oceans, where they feed on fish, squid, and other marine creatures. Their streamlined bodies and strong tails enable them to swim swiftly and gracefully through the water.
