Oligochaeta (/ ˌ ɒ l ɪ ɡ ə ˈ k iː t ə,-ɡ oʊ-/) [1] is a subclass of soft-bodied animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms.
Hirudinea is monophyletic, but the clade is embedded among the Oligochaeta. Two approaches are possible: [11] abolish Oligochaeta as traditionally delimited in favor of a number of smaller monophyletic lineages [11] treat Oligochaeta and Clitellata as synonymous while splitting up the traditional "oligochaetes" into monophyletic lineages.

An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida.The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta.
Oligochaeta is a genus of Asian flowering plants in the tribe Cardueae within the family Asteraceae. [2] [3] [4] Oligochaeta is native to central, southern, ...
Earthworm with clitellum lablelled. Close-up of the clitellum of a Lumbricus rubellus. The clitellum is a thickened glandular and non-segmented section of the body wall near the head in earthworms and leeches that secretes a viscid sac in which eggs are stored. [1]
Opisthopora is an order of mostly terrestrial worms. [1] [2]It is an order of the subclass Oligochaeta, which is distinguished by meganephridiostomal, male pores which open posteriorly to the last testicular segment. [3]
A new study says the flu A viral strain can adapt shape to stay infectious. Infectious disease doctors break down what this means and how to protect yourself.
Thus, the Haplotaxida might eventually be up-ranked to subclass status within the Clitellata or an expanded Oligochaeta, with the present suborders advancing to order rank. The latter – though without merging the Oligochaeta and Clitellata – has been proposed time and again in the past, most prominently for the distinct Moniligastrina.
