Abstract: | Gross structure and dimensions of the gills have been examined in a hill-stream sisorid catfish,Glyptothorax pectinopterus, which remains adhered to rocks by means of an adhesive organ developed on the ventral side of the thorax. The fish shows
a greater weight-specific gill area and greater length of the gill filaments by comparison with other hill-stream fishes.
Adaptation for life in a hill-stream habitat is shown by the presence of additional filaments on the gills and patches of
specialised cells on the filament epithelium. |
