Big Blue Octopus Octopus cyanea  occurs in the tropical Indo-Pacific from eastern Africa to the Hawaiian Islands in a depth range from 0-150m, max. mantle length 22cm with arms to at least 80 cm. \nBig blue octopuses are found living in muddy, sandy, or rocky bottoms, and in seagrass beds. They create lairs or dens in crevices or coral rubbles within coral reefs. These dens aren't used for long term; on average individuals spend up to 35 days in one den. The average lifespan of big blue octopuses is 12 to 15 months.\nThis juvenile specimen was encountered in the Triton Bay, Indonesia \n3°54'41.052 S 134°7'18.204 E at 12m depth

Asthenosoma varium is a large urchin (25 cm) with flattened, flexible test (the plates are articulated rather than fused). Very mobile, short spines, arranged in rectangular areas, separated by spineless areas. Spines have a blue swelling close to the tip, filled with venom.Living in bay, lagoon, external reef; on sandy or rubble bottoms. The flexible test allows, changing the shape, to enter very narrow crevices. The swollen shape of the spines and the flexible test are unique features. \nAsthenosoma varium sting can be very painful, a strong local pain due to venom injection can last for hours.\nThis specimen was encountered in a very shallow tunnel in the Triton Bay, Indonesia \n3°54'51.39 S 134°7'24.81 E at 2m 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.

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
