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!
What? I had no idea they could get that big. Do you know if they can be aggressive? You always heard about dolphins being friendly.
Dolphins arent known to be aggressive toward humans but they do go after theyre prey! They use conical shaped teeth to catch the fast moving prey!
