Crassiclitellata (common name, earthworms)[1] is an order of annelids belonging to the class Clitellata.[2].
Despite its common name, not all crassiclitellata are what most people mean when referring to earthworms- those are the species that belong in this order's lumbricidae family, whose Lumbricus terrestris species represent the standard garden worms and nightcrawlers familiar to most people
Etymology
[edit]This order's name, crassiclitellata, can literally mean "thick saddle." Broken down, "crassi" from Latin word for "thick" or "fat," and "clitellata," stemming form the Latin word for a raised bump, signifying the band near the head of the worm.[3][4] Thus, this order can be characterized by the types of annelids whose clitellum is more bulbous than the rest of the Clitellata class.
Families
