Tasselled Wobbegong Eucrossorhinus dasypogon occurs in Eastern Indonesia, Papua New Guinea and Northern Australia. This ovoviviparous species can reach more than 3.5m length, common length is less than 2m. The tough skin is used sometimes for leather. Tasselled Wobbegong is threatened by extensive coral reef habitat destruction (pollution and dynamite fishing), as well as expanding fisheries. A considerable section of its habitat is protected in the Great Barrier Reef Marine Park. This specimen lies at the sandy bottom in an outer reef east of Kri Island. This shark species is primarily nocturnal. It\

In large aggregations, Yellow Sea Cucumbers Colochirus robustus are often misidentified as corals. Colochirus robustus occurs in the tropical Central Indo-Pacific in a depth range from 1-25m, max. length 7cm. When feeding, the species extends the branchy feeding arms into the current. There are multiple reproduction options; instead of spawning, when getting large, the species can split into two: In a few days, the head end is ready to leave, whilst the rear end takes about a week to grow an own head! \nThese specimen aggregate on an old whip coral overgrown by sponges, hydroids and ascidians. \nTriton Bay, Indonesia \n3°55'0.858 S 134°6'6.102 E at 12m depth

Indian Feather Duster Worm Sabellastarte spectabilis occurs in the tropical Indo-Pacific Ocean from the Arabian Sea to Hawaii in intertidal and subtidal reefs in a depth range from 3-30m. It is quite a large species, with a tube up to 30cm and a single crown of about 10cm in diameter, feeding by filtering plankton and organic particles from the water column. \nAs a defence mechanism, these creatures are able to quickly retreat into their tubes, when disturbed by potential predators. It may come as a surprise, but Sabellastarte has eyes! \nCrowns of this species often have a banded pattern in a variety of colors including browns, red, white and yellow. Yellow  like this specimen  is the rarest color for this species. \nTengah Island, Indonesia, 5°8'44.496 S 132°0'46.254 E at 8m depth by night
