Whales

Whales are the biggest animals in the history of the world. Even the LARGEST of the dinosaurs the Brachiosaurus, was less than half the weight of the Blue Whale. Whales look like fish but aren't. Unlike fish they have lungs and they need to go to the Surface to breath. There are three categories of whales: baleen, toothed, and those that are just typically extinct. No studies of whales would be complete without listening to beautiful whale song , and this is where the Internet excels.
