High-hat Triplefin Enneapterygius tutuilae occurs in the tropical Indo-West Pacific from East Africa to Micronesia, Line Islands, and Society Islands, and Taiwan to Australia, including Papua New Guinea, Line Islands and Society Islands, Taiwan to reefs of Coral Sea and New Caledonia in a depth range from 0-55m, max. length 4cm. Adults are found in various reef habitats, but often on sponges or reef outcrops and in intertidal pools and on corals and rocks. The species feeds on zooplankton. \nEven if it is the most common and most widely distributed among Enneapterygius species, this tiny and well camouflaged fish is rarely encountered. \nTriton Bay, Kaimana Regency, West Papua Province, Indonesia \n3°54'41.0503 S 134°7'18.2052 E at 4m depth

The roundworm, Contracaecum rudolphii, is a parasitic nematode belonging to the family Anisakidae. Fish are by far the main source of infection as they serve as intermediate host of the nematodes. The final hosts are marine mammals (e.g. seals) or piscivorous birds (e.g. cormorants and pelicans). Identification of these nematodes is important in terms of seafood safety and public health, as humans may be infected following consumption of infected seafood.
