The worms use their spiral, tree-like appendages (called radioles) for … Christmas Tree Worms average only about 1.5 inches in length. These Christmas tree-like crowns are composed of radioles, or hair-like appendages radiating from the worm’s central spine.

These cone-shaped worms are one of the most widely recognized sedentary polychaete worms. The Christmas tree worm (Spirobranchus giganteus) is a type of polychaete, a group of segmented worms mostly found in the ocean.

Its body is encased in the protective pouch, and the feathery spirals either extend outwards, or retract into their opening. However, because of their distinctive shape, beauty, and color, these worms are easily spotted. When startled, Christmas tree worms rapidly retract into their burrows, hiding from would-be predators.Christmas tree worms come in a variety of bright colors.

They have been known to occur from the Caribbean to the Indo-Pacific.Few organisms are known to feed on tube-borne polychaetes and While the worm itself has no commercial fishery importance, it is of interest to marine aquarists and divers. When the worm retreats into its tube, the opening is shut using an operculum, whic… The worms' most distinct features are two "crowns" shaped like One major difference between Christmas tree worms and the closely related Christmas tree worms are widely distributed throughout the world's tropical oceans.

Christmas tree worms, Spirobranchus giganteus, are Christmas tree-shaped serpulid tube-dwelling worms with magnificent twin spirals of plumes used for feeding and respiration. The variously colored worm crowns make extremely popular underwater photographic subjects for As the species is widespread and relatively common, no conservation efforts focus on this species (or polychaetes in general). The Christmas-tree worm does not drill, or dig holes in the coral’s skeleton, it settles on the coral’s living tissue cells, building a calciferous pouch framework on the coral. 3. It lives on tropical coral reefs and resembles a … S. giganteus usually settles onto an existing head of living coral before secreting its tube, thereby increasing its level of protection as coral tissue overgrows the calcareous tube. A table included below, shows visual census data of partially and totally consumed Porites colonies. They are found throughout the tropical oceans, including the Caribbean and the Indo-Pacific.

In this study, the researchers first established the possibility of a mutualism by recording observational data. They are some of the most widely recognized polycheates, or marine burrowing, segmented worms out there. 2. They come in many colors including orange, yellow, blue, and white and, though they are small with an average 3.8cm in span, they are easily spotted due to their shape, … The Christmas tree worms protect the coral from predation by the Crown of Thorns Starfish (Acanthaster planci)5. S. giganteus is commonly found embedded entirely in heads of massive corals, such as stony corals Porites and brain corals.
