For example: jellyfish it is not made of jelly, nor a fish, slowworm it is not a worm, to avoid this, latin scientific names are used which started in the 18th century by carolus. Classifications: related species are grouped into the same genera (singular genus, genera group into families, families group into orders, orders group into classes, classes into phyla, phyla into kingdoms, and more recently kingdoms into domains.
