Insects outnumber other animal types in a number of ways. No one knows how many species of insects there are but estimates range from two million to eighty million. The low estimate still far outnumbers any other living thing. There are also more individuals of insects than other animals. Honeybee colonies can have populations over 50,000 and ant colonies can be even larger.
Insects also win when it comes to weight.
If you weigh all the animals in one acre of land insects will usually make up the majority of the total weight. Insects can be found in almost any environment on earth, though they have not inhabited the ocean with much success. Some insects breed in tide pools and there is even a water strider that can be found skating across the open ocean. The ocean domain has been left to the insect s cousins, the crustaceans. Insects are masters of land, air and fresh water.
