Delfine, commonly known as dolphins, are highly intelligent marine mammals belonging to the family Delphinidae. They are known for their playful behavior, social structures, and advanced communication skills. Dolphins are found in oceans and seas worldwide, often living in groups called pods. These creatures are characterized by their streamlined bodies, which allow them to swim swiftly. 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 and performing flips, which can be a form of social interaction or play.
