Animals

The structure of the platypus' eye indicates that over the years of evolution they have been adapted to an aquatic and nocturnal lifestyle.

It is closely related to an extinct giant aye-aye (Daubentonia robusta).

They are omnivores.

The Arabian oryx was already known to the ancient Egyptians.

In 2003, a complete list of birds on which cuckoos parasitize was published by Alexander D. Numerov.

The Male takes care of the young.

They make their nests on the ground or in trees, usually near the shore, although this is not the rule.

These spiders are known in Europe mainly from the fact that they sometimes appear in bananas sold in markets.

The distinctive feature of this bird is its huge bill. Not everyone liked its appearance, however. The French naturalist Georges-Louis Leclerc de Buffon called the beak of the toco toucan a "gross monstrous" addition.

The many genera of wolf spiders range in body size from less than 10 to 35 mm (0.4 to 1.38 in).
