“Sunday Morning” takes us among some spotted dolphins in the blue waters off the Bahamas. Videographer: Mauricio Handler.

Atlantic spotted dolphins are found in warm temperate and tropical waters of the Atlantic Ocean. They usually form groups of five to 50 individuals but sometimes travel in groups of up to 200. They are fast swimmers and often “surf” in the waves created by vessels.

Young Atlantic spotted dolphins do not have spots. As a result, they can look like slender bottlenose dolphins. Their distinctive spotted pattern starts to appear all over their bodies as they get older.
