Common Dolphins vary so greatly in appearance that at one time or another as many as 20 different sub-species have been suggested. The Common Dolphin is often mistaken for other kinds of dolphins. They can best be recognized by their slim, streamlined bodies, with an hourglass pattern and yellow patch on their sides. They range from 6-8 feet (1.7-2.4 meters) long, and weigh between 115 and 245 pounds (70 to 110 kilograms).
