Mediterranean fanworm (Sabella spallanzanii), also known as the feather duster worm.
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
Sabella spallanzani is a species of marine polychaete worm commonly known as the European fan worm or feather duster worm. It belongs to the family Sabellidae and is widely distributed in the coastal waters of the Mediterranean Sea and the northeastern Atlantic Ocean. The worm has a slender and elongated body that can reach lengths of up to 30 centimeters. Its most striking feature is its ornate crown of feathery, fan-shaped tentacles called radioles, which are used for filter-feeding and respiration. The radioles come in various colors, including shades of white, yellow, orange, and pink, adding a vibrant touch to the underwater landscape. Sabella spallanzani is a fascinating and beautiful creature that contributes to the biodiversity of marine ecosystems.

Gorgonian Wrapper Nemanthus annamensis, a species of Sea Anemones, is a common commensal on gorgonian sea fans and sea whips in Central Indo-Pacific water deeper than 10m. Sea anemones can contract and bend the column in various directions. The Gorgonian Wrapper's muscles can also be used to expand the column and tentacles by using hydrostatic pressure. This is called a hydrostatic skeleton. Gorgonian Wrappers can detach themselves from the bottom and relocate. Pantar Island, Indonesia, 8°12'51\
