Sperm whales are part of the energy flow too. Visit the Mysterious Everything section. Go to the Next Dr. Galapagos Question . The picture shows a whale with teeth in the top and bottom jaws. Most sperm whales only have teeth in the bottom jaw.
Some males have a few teeth in the upper jaw but nothing like what's shown in the picture.
One source suggests the teeth are more for fighting amongst males or for defense than for eating. Young sperm whales often don't sprout teeth until some time after they have started feeding themselves. In some females the teeth never come out. All rights reserved.
