Abstract
The ultrastructures present in the scales of Glossogobius aureus were subjected to morphological analysis using a Leica ES2 stereomicroscope in tandem with an Olympus digital camera with a 12.1 megapixel resolution and a 5x optical zoom. The female scales were typically of a ctenoid type whereas the male scales showed the presence of cycloid and ctenoid types. The study described 21 scale morphotypes in the male species while 24 morphotypes were described in the female species. These morphotypes were categorized into main, regenerated and specialized scale types. Differences in scale morphology between sexes are best described by the variation in the characteristics of its fully developed scales.
Highlights
Goby fishes belong to the order Perciformes and family Gobiidae
The aspects of body morphology in G. aureus have been described in detail by (Akihito and Meguro, 1975b) and the biology and its ecology have been accounted in the information provided (Akihito and Meguro, 1975a) but there is still a need to have other means of clearly described species
It is interesting to note that the scales of the male were of cycloid and ctenoid types (Fig. 3B, C)
Summary
Goby fishes belong to the order Perciformes and family Gobiidae. The species are identified by the presence of a fused pelvic fin at the anterior portion of the body which serves as a suction disc to enable them to dwell at the bottom attaching themselves to rocks or reefs. They have distinctive 2 dorsal fins: dorso-anterior spines and dorso-posterior soft rays. Its high level of endemism made gobies a significant factor in considering our local biodiversity (Bagorodsky et al, 2010; Sanda and Kovacic, 2009). The aspects of body morphology in G. aureus have been described in detail by (Akihito and Meguro, 1975b) and the biology and its ecology have been accounted in the information provided (Akihito and Meguro, 1975a) but there is still a need to have other means of clearly described species
