Out of the water, Giant Mudskippers (Periophthalmodon schlosseri) are right at home on the mudflats. To breathe on land, they store seawater in their modified gill chambers and absorb oxygen through their skin.
Giant Mudskippers are aggressive hunters of crustaceans and smaller fish. In turn, they are preyed on by birds like herons and kingfishers.
