Bihunichthys Kottelat & Lim, 1994 Chaudhuria Annandale, 1918 Chendol Kottelat & Lim, 1994 Garo Yazdani & Talwar, 1981 Nagaichthys Kottelat & Lim, 1991 Pillaia Yazdani, 1972 Pillaiabrachia Britz, 2016 [1] 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, the others have been only recently reported (since the 1970s), all in the eastern Asia area, from India to Korea.

[2] 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.

The family name "Chaudhuriidae" comes from a Burmese local name for a fish.
