Earthworm eel
Template:Short description Template:Automatic taxobox
Chaudhuriidae, is a family of small freshwater eel-like fish related to the swamp eels and spiny eels, commonly known as the earthworm eels. The known species are literally the size and shape of earthworms, thus the family name. While one species, Chaudhuria caudata was reported from the Inle Lake by Nelson Annandale in 1918,<ref>Template:Cite journal</ref> the others have been only recently reported (since the 1970s), all in the eastern Asia area, from India to Korea.<ref name=FB>{{#invoke:Cite taxon|main|fishbase|genus=|species=|subspecies=}}</ref>
Neither the dorsal nor anal fins have spines, and in Nagaichthys and Pillaia they have fused with the caudal fin; in the other genera, the caudal is small but separate. Their bodies have no scales. The few specimens found to date have been no longer than Template:Cvt, and Nagaichthys filipes is only known to reach Template:Cvt. The eyes are small, covered in thick skin.<ref name=Britz2003>Template:Cite journal</ref> Almost nothing is known of the habits and biology of the earthworm eels.
The family name "Chaudhuriidae" comes the genus name Chaudhuria, expanded to family level. Both names honour B. L. Chaudhuri (d. 1931) for his assistance in writing the initial paper that erected both the genus and family.<ref name = ETYFish>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
