Diurodrilus is a genus of tiny marine animals that has traditionally been assigned to the annelid worms, although this affinity is not certain. With a maximum length of 0.45 mm, it has an unusual morphology with many traits not found in other annelids, including a ventral creeping foot.[1][2] Analyses of DNA have both refuted and supported placement within the annelids,[2][3] with the unusual morphology perhaps due to evolutionary progenesis, in which organisms develop sexual maturity while retaining the larval traits of their ancestors.[3]
The following species are recognised:[2][4]
- Diurodrilus minimus Remane, 1925
- Diurodrilus ankeli Ax, 1967
- Diurodrilus benazzii Gerlach, 1953
- Diurodrilus dohrni Gerlach, 1952
- Diurodrilus subterraneus Remane, 1934
- Diurodrilus westheidei Kristensen & Niilonen, 1982
