Tube Anemone Cerianthus filiformis is a species of marine Cnidaria in the family Cerianthidae. \nThe species is widespread throughout the tropical waters of the Indo- West Pacific in a depth range from shallow to 100m, has a stretched and muscularised body which can reach 35cm.\nCerianthus filiformis lives in a mucous tube which is sunk in the soft substrate The animal shows only its tentacles to feed, usually at night time. The species feeds on small planktonic organisms, tiny crustaceans, larval forms, and other minute organisms drifting in the water column. The long, slender tentacles of Cerianthus filiformis are equipped with cnidocytes (stinging cells) that help capture prey. \nLembeh Strait, North Sulawesi, Indonesia \n1°29'59.244 N 125°15'40.794 E at 11m depth

The appearance of this pretty coral belies its aggressive behavior. Many individual coral polyps form colonies which join together at the base of their skeletons. These colonies grow to form branches, columns, solid colonies that are dome-shaped, or colonies that adhere close to the substrate. Colonies may be meters across and sometimes whole sections of a reef face are covered exclusively by one branching Goniopora species. Goniopora lobata, daisy coral, is named for its extremely large, flower-like polyps, and can grow to cover areas of six to ten meters. Each polyp has 24 long and fleshy tentacles that are normally extended day and night, although these quickly retract when touched revealing the massive skeletons beneath. Each Goniopora species differs in the shape and colour of their polyps, which allows their identification underwater. \nThe species occurs in the Indian and Pacific Oceans; from the coast of Mozambique, to the Red Sea, and east to northern Australia, southern Japan and Hawaii. \nFlowerpot corals are most commonly found in turbid water protected from strong wave action.Flowerpot corals are capable of developing elongated sweeper polyps, like the sweeper tentacles of other corals, which can inflict severe tissue damage on a coral within their reach. It is therefore unusual to see other coral species growing close to the flowerpot coral, and it is believed that this adaptation benefits the flowerpot coral in the intense competition for space on the reef. \nFlowerpot corals have separate male and female colonies (not all corals do) which release sperm and eggs into the water for external fertilisation. The fertilised egg develops into a free-swimming larva that will eventually settle on the substrate and develop into new colonies.\nTriton Bay, Indonesia \n3°54'52.062 S 134°7'21.384 E at 17m depth
