The objective of this study was to determine the effects of feeding on the excretory nitrogen (N) metabolism of the giant mudskipper, Periophthalmodon schlosseri, with special emphasis on the role of urea synthesis in ammonia detoxification. The ammonia and urea excretion rates of P. schlosseri increased 1.70- and 1.92-fold, respectively, within the first 3 h after feeding on guppies. Simultane...

considerable amounts of different pollutants, especially crude oils, are present in the persian gulf and its northern region, so biomonitoring the effect of these pollutants on its biota is necessary. ethoxyresorufin o-deethylase (erod), gluthathione s-transferase (gst) and catalase (cat) activity were measured from biochemical level in the gills of mudskipper periophthalmus waltoni collected f...

Two species of mudskipper are identified with different behaviours, which related to their pelvic fin morphologies. Periophthalmus variabilis has unfused fins and is capable climb on the vertical substrate. Another species, Boleophthalmus boddarti fused supports fish mobility across muddy In context anatomy, both composed a frenum covers girdle rays (lepidotrichia). The P. split that not interc...
