Why are insects so small?
The creatures of the Earth have different sizes. All of vertebrata, mollusk, worms, insects, belong to the animal kingdom. But we see that their individual kinds show extreme variations in size. The largest animals, such as whales and giraffes belong to the class of Mammalia, and the smallest ones, i.e. insects and Acarina belong to Arthropoda. Largeness and smallness are relative qualities. A thing, on its own, cannot be large or small, and only by comparison with other things, becomes large or small.
