Kryptopterus is a genus of catfishes belonging to the family Siluridae. They are found in freshwater throughout Southeast Asia. The scientific name comes from Ancient Greek kryptós (κρυπτός, "hidden") + ptéryx (πτέρυξ, "fin"). It refers to the reduced or even entirely absent dorsal fin of these catfishes.[1]
These small- to medium-sized catfishes often have transparent or translucent bodies, hence their common name Asian glass catfishes. Most significant among these is the Ghost Catfish (K. minor), which is the "glass catfish" most often seen in the aquarium fish trade. It is frequently misidentified as its larger relative the Glass Catfish (K. bicirrhis), which is, however, rarely if ever traded. This was only realized in 1989, however; earlier authors assumed K. minor to be K. bicirrhis by default.
