What is an Insect?
Insects are invertebrates which belong to the phylum of animals called arthropods. There are more species of insects than any other class of living organism; an estimated 2000000 species of insect exist on the Earth today.
Arthropods are invertebrates which have an exoskeleton covering their bodies. This exoskeleton is jointed so that the legs and segments can move. As well as the insects there are four other classes of Arthropods: the arachnids (spiders, mites and scorpions), the crustaceans, the millipedes and the centipedes.
