This may suprise you but dolphins are warm blooded mamals just like you and me. This might sound odd but they have cone shaped teeth. Dolphin pregnancies last 6 months. The new born dolphin is only 2-3 feet long. As soon as it is born it is pushed to the surface for air. There are 37 different speicies and most of them eat fish. The average size of a dolphin not including the killer whale is 6 feet and the average weight not including the killer whale is 100 pounds. The reason that the killer whale wasn't included is because it is 30 feet long and weighs more than 100 pounds. To find out more look at the other pages on this web-site.
