Each species of grasshopper has its own song. This is important, as the varied species cannot breed with each other. The female needs to be aware that she is listening to a male from her own species.
Compass termites of Northern Australia build tall nests that are wedge-shaped. They measure up to 3.5 m in length.
Flying frogs change color in the day. They are greenish-blue in sunlight and green in the evening. At night there are black.
Boas, as well as many other snakes have special heat-sensitive organs that are called pits. These pits are on their heads. They can detect the heat given by a warm-blooded animal standing close to them.
The king Cobra can grow to the length of 5.5 m, and is regarded as the largest poisonous snake in the world. A tiny amount of its poison can kill up to 30 people.
Anteaters protect their long claws by walking on their knuckles. This makes them look as if they are limping.
Bats eat all types of food. There is no restriction where their diet is concerned.
The hippopotamus’s eyes, ears and nostrils are on the top of its head. This enables it to stand or sit, almost completely covered by water with as little as possible showing above the surface.
The hippopotamus’s skin is protected by its own pink oily secretion known as ‘Pink sweat’.
