| Abstract: | The microvasculature of the pseudobranch in Anabas testudineus and the carotid labyrinth of Heteropneustes fossilis have been studied using scanning electronmicroscopy of Mercox-injected casts. Results confirm differences in origin and basic capillary structure. It is concluded that the pseudobranch is a glandular structure related to functioning of the eye whereas the carotid labyrinth of fishes is concerned with the regulation of fluid pressure and oxygen supply to the brain. |
