Bottlenose dolphins are marine mammals known for their intelligence and playful behavior. They typically have a grayish color and can grow up to 12 feet long. These dolphins are found in warm and temperate seas around the world, often living in groups called pods. They communicate using a variety of clicks and whistles, which helps them coordinate while hunting and socializing. Bottlenose dolphins primarily feed on fish and squid, using echolocation to locate their prey. They are also known for their acrobatic displays, often leaping out of the water. These dolphins are popular attractions in aquariums and marine parks, contributing to research and conservation efforts related to marine life.
