Still so many undiscovered critters out there!
Should I make a trip to a remote part of Asia or South America to collect some fish?

๐๐๐กโ๐๐๐๐โ๐กโ๐ฆ๐ ๐๐๐โ๐, a new species of phreatobitic swamp eel (Synbranchidae), is described from wells in a small village in Goalpara District, Assam, northeast India.
"The discovery of ๐
. ๐๐๐โ๐ from wells in the same village in which ๐บ๐๐ก๐โ๐๐ ๐๐๐๐๐๐ Britz et al. was recently described highlights the presence of a formerly unknown and highly dynamic subterranean habitat: the groundwater aquifers in alluvial deposits in northeast India."
Phreatobitic refers to organisms (phreatobites) that live exclusively within the phreatic zone, which is the subterranean area of groundwater aquifers completely saturated with water.

๐๐๐กโ๐๐๐๐โ๐กโ๐ฆ๐ ๐๐๐โ๐, a new species of phreatobitic synbranchid is described from wells in a small village in Goalpara District, Assam, Northeast India.
It is distinguished from the northeastern Indian ๐

. ๐๐๐ ๐๐๐, ๐
. ๐๐๐๐๐๐ ๐ ๐ข๐ , and ๐

. ๐๐๐โ๐ is distinguished by several anatomical characters.
