| 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. | ||||
