Abstract: | The epidermis of the torrent catfish, Liobagrus mediadiposalis, consists of three layers: the outermost layer, middle layer and stratum germinativum. The epidermis consists of two types of skin glands, small mucus cell and voluminous club cell. The unicellular mucus cell contains acid sulfomucins (some sialomucins) and the club cell, sometimes binucleate, is proteinaceous. Well-developed vascularization is one of the characteristics of epidermis of L. mediadiposalis. Well-developed lymphatic spaces contain lymphocytes in the epidermis. The dermis lacks scales and consists mostly of a thick, dense connective tissue; its superficial region just below the basal membrane is supplied with fine blood capillaries. These histological features of the skin in L. mediadiposalis are consistent with that required for cutaneous respiration. |
