Are hyenas dogs?



No, though they looked quite similar. Hyenas hunt in packs like dogs, but they have four toes per foot, whereas dogs have five on their front paws. Hyenas are not cats either, but are closely related.

What is a Tasmanian devil?



The Tasmanian devil lives in Tasmania, an island south of mainland Australia, and belongs to the same mammal family as kangaroos, carrying its babies in a pouch on its tummy. It's small, ferocious, and can defend itself well against other predators.

Amazing!


There were mammals around at the same time as the dinosaurs. Just like dinosaurs, some were carnivorous (meat-eating), such as Zalambdalestes, and some were herbivores (vegetarians).

Cats, dogs and bears are the only carnivores in the world?



Is it true?


No. Many other mammals, such as hyenas, weasels, raccoons and humans eat meat. So do other animals - birds of prey, some reptiles and sharks in the sea.

What do cats, dogs and bears have in common?


They are all mammals. This means that they are covered with cosy fir and feed their young with mother's milk. Cats, dogs and bears are also all carnivorous, which means they eat meat. To do this, they have special sharp, pointy teeth, called canines.

Mosasaurs - The largest lizards ever!



Amazing! 

The largest lizards ever were Mossasaurs, huge reptiles that swam in the sea. They were real sea monsters - ten metres long with huge mouth, and they looked like dragons! They probably ate anything they could catch.

Were there dinosaurs in the sea?




Were there dinosaurs in the sea?



No. All dinosaurs lived on land, but there was a variety of strange reptiles that swam in the seas in dinosaur times. Ichthyosaurs were strong swimming reptiles that looked like dolphins and could breathe air. They probably hunted in packs, feeding on fish and squid.

Dinosaurs only lived on land?







Is it true? 








Yes. They were adapted for life on land because they walked with straight legs tucked underneath their bodies, as we do. This gave them an advantage over other animals and helped them dominate the land.
