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

Holothuria forskalii, also known as the black sea cucumber or cotton-spinner, is a species of sea cucumber in the family Holothuriidae. It is found at shallow depths in the eastern Atlantic Ocean and the Mediterranean Sea. It was placed in the subgenus Panningothuria by Rowe in 1969 and is the typetaxon of the subgenus.\n\nThis sea cucumber has a cylindrical body and can grow to thirty centimetres long. It is usually deep brown or black but sometimes has an underlying yellowish mottling, especially on the underside. The skin is soft yet coarse and tough and is covered with fleshy papillae which are often tipped with white. The papillae are believed to be sensory organs sensitive to touch and possibly to chemicals dissolved in the water. The underside has three rows of tube feet for walking and climbing while the upper side has two rows of rudimentary suckers.\n\nHolothuria forskalii is a deposit feeder, meaning that it feeds on organic matter that is found in the sediment. It uses its tube feet to move around the seabed and its tentacles to collect food. The tentacles are covered with mucus that helps to trap small particles of food. The food is then transported to the mouth, where it is broken down and digested.\n\nHolothuria forskalii is a hermaphrodite, meaning that it has both male and female reproductive organs. When two individuals mate, they exchange sperm and eggs. The eggs are fertilized externally and develop into larvae. The larvae are planktonic, meaning that they drift with the currents. After a period of time, the larvae settle on the seabed and metamorphose into juvenile sea cucumbers.\n\nHolothuria forskalii is an important part of the marine ecosystem. It helps to recycle nutrients and to keep the seabed clean. It is also a food source for a variety of marine animals, including fish, crabs, and sea turtles.

Celestial Phyllidia Phyllidia coelestis occurs in the tropical Indo-West Pacific from South Africa to the South China Sea and Australia to Fiji and from Philippines to Vanuatu, max. length 6cm. The species has the mating behavior of the members of the order Nudibranchia; they are simultaneous hermaphrodites: both individuals darts their penis toward each other to induce one to act as a male and the other as the female. The victorious one to penetrate the body wall is the dominant male. Thats how simultaneous hermaphroditism works. Palau 7°5'12.18 N 134°15'34.77 E at 4m depth
