The sea life at Little Manuk, a so called rocky islet, is very interesting. Bubbles escape through the sand and rocks in places. Apparently there is still some volcanic activity. In the shallow areas there are slopes with black sand and tumbled rocks covered by algal turf and small hard corals, including large rocks with attached table Acropora between four and five metres depth. Hard coralc cover almost 80% and the stress resistance, recovery, and overall reef health and resilience potentials of this coral community are all high. \n\nA large Barrel Sponge Xestospongia testudinaria at the left, an impressing variety of coral genera and species, many fish spies as wrasses, damselfishes, Soldiers, Surgeons are there, Hydroids, Zoanthids, Tunicates  the biodiversity is high. \n\nLittle Manuk near Tayandu Island, Indonesia \n5°28'6.876 S 132°15'26.808 E at 19m depth
Mandarin fishes inhabit shallow protected lagoons and inshore reefs. They occur in the Western Pacific from Ryukyu Islands to Australia, usually in small groups spread over small area in a depth range from 1-18m, max. size 7cm. \nMandarinfish do not have scales, but a mucus layer for protection. It is not only a stinky slime they produce, but they also secrete a toxin to protect them against predators. Their dramatic colouration, known as aposematism, is a warning: unpalatability and toxicity - both prey and predator get to live longer. \n\nThis specimen was encountered in the Lembeh Strait, Indonesia \n1°27'34.836 N 125°13'17.046 E at 4m depth by night

There are a lot of Sinularia Leather Coral there, but the yellow Gorgonian Corals dominate the scenery. \nGorgonian sea fans are Cnidarians that build colonies in branching formations that usually are fan-shaped, thus the common name. Gorgonians are octocorals: each polyp has eight pinnate tentacles which it uses to capture nutrients suspended in the water column. They are seen most often on reef crests, or jutting out from drop-offs or steep banks in locations where natural currents will sweep plankton and other organic nutrients across the polyps tentacles. \n\nTriton Bay, Kaimana Regency, West Papua Province, Indonesia, \n3°57'58.68 S 134°9'6.27 E at 13m depth
