My favorite mammal is a dolphin! There are so many kinds of dolphins that are widely distributed around the world!
Fun! I once seen a pack of porpoises while boating. I think they're in the same family as dolphins?  
Yes they are! There are actually 40 species of dolphins to be exact!
Wow, have you seen many different kinds?
Personally no, not close up, which is odd considering I live in Florida and that dolphins can range from the size of relatively small to the size of a killer whale!
