Insect
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Insects are a group of invertebrate animals. They are the biological class Insecta.
Insects have exoskeletons (skeletons on the outside), and their body has 3 segments: head, thorax, and abdomen. Most insects have six legs and four wings, such as dragonflies. Insects are the biggest group of animals on earth, and there are more than 800,000 kinds (or species) of them. Insects are part of the phylum arthrapoda (arthropod). All insects are classified by the fact that they have 3 pairs of legs, and usually have 2 pairs of wings.
Contrary to what some people believe, spiders, scorpions and similar animals are not insects, they are arachnids. Arachnids are arthropods that have 4 pairs of legs.
