The Toothed Whales are made up of toothed whales and dolphins. They use echolocation to find their food. They do this by sending a signal out in the water and then detecting what it has bounced off of. This way they can find out how far away their prey is, how big it is, etc. These whales and dolphins are also thought to be very highly intelligent. The following are some pictures:
