Abstract:
Concerning the importance of scale morphology in fish taxonomy, scale ultrastructure of tank goby fish Glossogobius giuris from Makran basin of Iran, was studied using scanning electron microscopy. Scales from below the dorsal fin and from the head region were removed, cleaned in potassium hydroxide solution and were prepared for the scanning electron microscopy. Variations are found in scale morphology of this fish in different body parts. Ctenoid and cycloid scales are present on the head and body regions, respectively. Focus which is located in the posterior part of scale, is clear and has mucous pores. Rradii are found only on the anterior part of scale and numbers of primary radii are more than the second and tertiary radii. These radii divide the anterior part of scale into several regions and thus the scale is sectioned. Tongues or lobes of the anterior part are distinct. Inter circular space is without granules and bifurcation is observed in some circuli. Absence of the lepidonts on the crest of circuli is another character of this fish scale. It seems that position and shape of focus, absence of lepidonts and arrangement of cteni on the scales of this fish could be used as important taxonomic characters.
