Hill streams are unique aquatic ecosystem characterised by shallow, narrow channels, low temperature. high altitude, different types of substratum, high current of water, hence the hill stream fishes develop mechanical devices to combat the force of water currents and are successfully adapted to this unique environment Development of various types of adhesive organs is one of the prerequisites for survival of these fishes, In Garra lamta the anchoring devices consist of true suckers. The Scanning Electron Microscopic structure of the adhesive disc of Garra reveals the presence of hexagonal epithelial cells with elevated cell boundaries. Scantly mucous gland openings have also been observed in the adhesive disc.
