There are large dolphins and small sharks. The largest of the dolphins is the Orca. It can reach lengths of 23 feet and weigh up to 4 tons. Great White Sharks usually come to mind when you think of big sharks. They have been found up to 20 feet long at weights of up to 2 1/2 tons. The largest shark alive is the plankton-eating Whale Shark. It will get up to 46 feet long and weigh up to 15 tons. A large Bottlenose Dolphin (made famous by Flipper) will be up to 8 feet long and weigh up to 660 pounds.
