Abstract: The epidermal mucus secreted by the epidermal cells of Bagridae fishes help to reduce the body friction against the water, play a vital role in maintaining the homeostasis and innate immune system to prevent the entry of invading pathogens. A preliminary investigation was carried out to isolate the epidermal mucus from two endemic and endangered Catfish species of Western Ghats viz., Hemibagrus punctatus and Sperata aorides. The isolated epidermal mucus of two catfishes were subjected to FT-IR analysis to find out the functional groups present in the mucus. The result of the present study revealed that the functional groups present in the mucus samples of two species are slightly varied. The alcohol as OH stretch at peak value 3900 – 3300cm^-1, primary amide is present as C═O stretching of proteins at 1643cm^-1 and secondary amide is present as N–H bending and C–N stretching of proteins at 1550 cm^-1, alkane as C=C bending at 680-670 cm^-1, halo compounds and iodo compounds as C-Br / C-Cl and C-I stretching at 670 – 400 cm^-1 are present in the epidermal mucous of the catfishes.
