Insecta

Insecta is a taxonomic class of animals. They contain an estimated 90% of Earth's species, having millions of species includedhttps://en.wikipedia.org/w/index.php?title=Insect&oldid=1110330555. Insecta contains only insects and may be the derivation for the name, but is undoubtedly linked. It comes from Latin insectum, which means segmentedhttps://en.wiktionary.org/w/index.php?title=insect&oldid=68527302. It is in reference to one of the features animals of this class usually have, which is three segmented body parts: the head, the thorax, and the abdomen. According to Wikipedia there is additional controversy as some animals previously classified as insects have additional features that bring them outside of the Insecta class and require a different category. These creatures all have internal mouth partshttps://en.wikipedia.org/w/index.php?title=Entognatha&oldid=1078925215. However, they are not all related, and some groups evolved independently of each other. Thus, insects, aside from their three body parts and six legs, perhaps should also be known only to include those with external mouth pieces, if we're to continue associating it with Insecta. However, those are not all of the restricted features of "insects", merely the ones taught for quick identification for non-scientists.
