Dolphins communicate using a variety of sounds, including clicks and whistles, and are known for their acrobatic displays, such as jumping and spinning out of the water. Dolphins are carnivorous and primarily feed on fish and squid. They often hunt in groups, using cooperative techniques to catch their prey. These animals are also known for their strong social bonds, often forming pods that can consist of a few individuals to several hundred, depending on the species.
