The common dolphin, scientifically known as Delphinus delphis, is a marine mammal found in warm and temperate seas worldwide. They are known for their striking hourglass pattern on their sides, which can vary in color from yellow to light gray. Common dolphins are social animals, often seen in large groups, and are known for their acrobatic displays, such as leaping and riding the bow waves of boats. These dolphins primarily feed on small fish and squid, using echolocation to locate their prey. They can reach lengths of up to 8.5 feet and are known for their high intelligence and playful behavior. Common dolphins are often studied for their complex social structures and communication skills.
