Sun Coral Tubastraea faulkneri is a large polyp stony coral from the family Dendrophyliidae. The species occurs all over the tropical Indo-Pacific Ocean in a wide depth range of 3-225 meters, often in greater densities on vertical walls and caves. \nThese corals are slow growers and they do not contribute to coral reef development. Unlike many tropical corals, they are azooxanthellate or non-photosynthetic, meaning that they do not live in symbiosis with zooxanthellae in their tissues, allowing them to grow in complete darkness as long as they can capture enough food, usually plankton. \nThey extend their translucent tentacles like these specimen, usually during the late evening and the night and during the day the tentacles are completely retracted, but not in this case: It is midday under a ledge, so it remains dark enough.\nLembeh Strait, Indonesia\n1°27'38.166 N 125°13'34.284 E at 1.5m depth at 11:57 AM

Mediterranean Horseshoe Tubeworm - (Protula tubularia)
Ptilosarcus gurneyi, the orange sea pen or fleshy sea pen, is a species of sea pen in the family Pennatulidae. It is native to the northeastern Pacific Ocean where it lives in deep water anchored by its base in sand or mud. It has received its common name because of its resemblance to a quill in a bottle of ink. Monterey Bay, California.

Mediterranean fanworm (Sabella spallanzanii), also known as the feather duster worm.
The Red Fanworm Protula bispiralis (ex. Protula magnifica) occurs in the tropical Indo-West Pacific from Westcoast Africa tu Australia. The spieces has with 38 whorls of spirally arranged branchial radioles, a tube diameter of up to 2cm and grows up to 30 cm. There are several common names like Red Hard Tube Coco Worm, Mopworm or Feather Duster. The species uses the feeding crowns to catch microplankton.\nLembeh Strait, Indonesia \n1°27'38.1666 N 125°13'34.2828 E at 8m depth

ispira sp. is a genus of marine bristleworm in the family Sabellidae. Its members were initially included in genus Sabella by Grube in 1851. In 1856, Krøyer described Bispira as a separate genus. Members of Bispira are defined by spirally-coiled, equally-divided branchial lobes.\n\nBispira sp. are typically found in shallow tropical and subtropical waters, where they live in tubes made of sand or mud. They are filter feeders, and their feather-like feeding tentacles are used to collect plankton and other small organisms from the water column.\n\nBispira sp. can grow to be several inches long, but most species are much smaller. They are often brightly colored, with a variety of patterns and hues. Some species, such as Bispira polyomma, are even iridescent.\n\nBispira sp. are not typically harmful to humans, but some species can produce a mild venom. This venom is not usually strong enough to cause serious injury, but it can cause some irritation to the skin.\n\nBispira sp. are a popular addition to aquariums, and they can be quite easy to care for. They require a tank with moderate water flow and a sandy or muddy substrate. They should be fed a diet of small live food, such as brine shrimp or mysis shrimp.

Protula tubularia
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 35 cm.\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°27'34.836 N 125°13'17.046 E at 8m depth by night
