ABSTRACT
The aquatic biology is considered one of most biologically diverse, in the nature due to its ability of adaptation with different environmental conditions. These adaptations are compatible with the aquatic body needs to use minimum energy. According to the Oxygen requirements, some of the fish appeared active and other appeared inactive. The gills are the major site of external environment adaptation. Although the gills are very important in fish respiration, the literature on the histological aspects of gills is limited to a few types of fish. In this study, two types of fish (Oscar fish and goldfish) were used; the Oscar fish and goldfish. The investigated morphological and histological studies were done on the characteristics of gills on both types of fish. The results showed that the gills of the Oscar fish had a big surface area compared with the surface area of gill in goldfish. The gills of Oscar fish had a modification to get a high amount of oxygen using less energy. The study concluded that the active fish need a big surface area on their gills to get high oxygen and it adapted to survive the external conditions.
