Mudskipper (Periophthalmus gracilis) in mud. This amphibious fish moves across land using its limb-like pectoral fins. It breathes on land using highly vascular sacs on its mouth and gills. Its skin contains cells that are filled with a watery fluid, which cushion its movements. Its protruding eyes are adapted for vision above the water. Photographed in a mangrove near Sandakan, Sabah, Malaysian Borneo.
