A study of the structure of the gills using light and transmission electron microscopy showed that though the basic organisation of the filaments and secondary lamellae is very similar to that of other bony fishes, there was also a number of unusual features. Most of the blood channels of the secondary lamellae remain embedded in the tissue of the primary lamellae. The secondary lamellar surface is increased by the presence of irregular expansions which may be referred to as tertiary lamellae. The presence of an unusual structure on one side of many secondary lamellae was observed; this structure might possibly be due to the presence of a parasite. The possible functional significance of these observations is discussed and indicates the need for morphometric and experimental investigation of the respiration of this species.
