Tasselled Wobbegong Eucrossorhinus dasypogon occurs in Eastern Indonesia, Papua New Guinea and Northern Australia. This ovoviviparous species can reach more than 3.5m length, common length is less than 2m. The tough skin is used sometimes for leather. \nTasselled Wobbegong is threatened by extensive coral reef habitat destruction (pollution and dynamite fishing), as well as expanding fisheries. A considerable section of its habitat is protected in the Great Barrier Reef Marine Park. \nThe species is primarily nocturnal. Usually, by burrowing into the sand and with sand on its fins, the sharks outline becomes almost completely invisible to prey. This specimen was encountered at 4m depth during night time just when leaving the bottom. The scare at the pectoral fin of this specimen is distinctive.\nTriton Bay, Kaimana Regency, Indonesia, 3°56'17.7941 S 134°7'10.2802 E at 4m depth
