The subject of the painting is the fish and other animals found in salt water across the top end of Australia. Kunwinjku people travel to the coast around Cobourg Peninsula, Murganella and Croker Island, which are situated in Western Arnhem Land, to hunt these animals. The wamba or shark is a common predator along the coast. The minmawurri or sea snakes are not eaten as they are venomous. The shark has been painted in the classic “x-ray” style with internal organs and backbone shown which is one of the hallmarks of Kunwinjku paintings in the rock art tradition.
