Dolphins and their complex social behaviors
Did you know that there are "26 living species", of dolphins swimming in the ocean? Have you ever heard that they are in the same family as a whale? They are actually called a "small cetaceans" or a "toothed-whales", scientists and biologists. Through their studies they found that they have advanced or complex personalities. Scientists believe that dolphins are truly remarkable and highly intelligent.
However, don't confuse them with "porpoises", which are generally "smaller" than a dolphin. Basically, dolphins are a part of the "Delphinidae" family and porpoises are a part of the "Phocoenidae" family. Also, dolphins have "conical shaped teeth" and porpoises have spaded-like shaped teeth". Another difference is that dolphins have a "distant break" in the "rostrum" and porpoises don't have one.
