The gill and skin morphometries of three mudskippers-Periophthalmus chrysospilos, Boleophthalmus boddaerti and Periophthalmodon schlosseri were studied and compared. Correlations were made between the morphometric parameters of these respiratory surfaces and the different terrestrial and aquatic affinities of the mudskippers with special reference to their capabilities to respire terrestrially . The natural preference of B. boddaerti for an aquatic environment can bc explained by their having the longest and greatest number of gill filaments amongst the three mudskippers studied. It also has the largest gill area and gill area: skin area ratio, indicating a greater role of its gills than its skin in respiration . Both P. chrysospilos and P, schlosseri have relatively lesser affinity to water as their gills are not well adapted for aquatic respiration. P. chrysospilos has the smallest total number of filaments and shortest total filament length. It also has smaller gill area: skin ratio than B. boddaerti, and exhibits the most rapid increase in skin area with respect to body weight. Thus, its skin appears to have a greater role in gaseous exchange than its gills. In P. schlosseri, the gill area : skin area ratio increases as the fish grows, suggesting that small fish depends more on its skin for gaseous exchange whilst branchial respiration is more important in bigger individuals.
