6. Fish Fish were the first backboned animals to appear on earth, and they form by far the largest group of vertebrates. Unlike the other major divisions of vertebrates, however, fish are not a natural group; instead, they are an informal collection of 4 classes that are only distantly related to one another. A typical fish breathes using gills, has a body covered with scales, manoeuvres using fins, and is ectothermic (cold-blooded). Most species live in either fresh water or the sea, but a few species move between both environments.

7. BIRD Laughing Kookaburra The largest of all kingfishers, the Laughing Kookaburra is known throughout Australia for its raucous call, which it delivers with partly opened bill pointing skywards and its tail cocked. In urban areas, it becomes quite tame and may even be fed by hand. Hear a Kookaburra call

8. mammals Aquatic Mammals Three groups of mammals have adapted to aquatic life, developing a streamlined body and the ability to stay underwater for long periods (although all of them return to the surface to breathe). The largest group are whales and dolphins. Like whales, seals and sea lions rely on subcutaneous fat to keep warm, but they have retained their fur, which is kept waterproof by an oily secretion. Sirenians (the manatees and dugong) live in warm coastal waters and estuaries and are the only herbivorous aquatic mammals. Cetaceans
