“…In most cases, the misinterpretation was caused by both an initial lack of knowledge and our usual antropogenic way of interpreting what we are looking at. For instance, the histriobdellid Histriobdella homari was reported as an ectoparasite of the branchial chambers of crustaceans (e.g., in Paris 1955or Clark 1956), mostly because of its leech-like shape, and was later confirmed as a host-cleaning mutualist (Jennings and Gelder 1976). Also, Eunice norvergica, a gall-forming eunicid (an a priori parasitic behavior), enhanced the growth of their cold-water corals hosts by favoring the joining of colonies and the development of reef patches in deep waters (Roberts 2005).…”

Symbiotic association between Solanderia secunda (Cnidaria, Hydrozoa, Solanderiidae) and Medioantenna variopinta sp. nov. (Annelida, Polychaeta, Polynoidae) from North Sulawesi (Indonesia)

A mimic scale-worm was found associated with the athecate hydroid Solanderia secunda, commonly found on reefs of the NW coast of North Sulawesi, Indonesia. The species resembled Medioantenna clavata Imajima 1997, which was originally described without any reference to a symbiotic mode of life and later reported to be living on a solanderiid hydroid both in Japanese waters. A detailed morphological analysis led us to consider the Indonesian specimens as a new species, namely Medioantenna variopinta sp. nov., which is congeneric with the Japanese species. The new species differs from the type material of M. clavata as it has elytra with one prominent finger-like papilla and all neurochaetae with unidentate tip, instead of an elytral lump and both unidentate and bidentate neurochaetae on segment two. In turn, the Japanese worms associated with Solanderia are here referred to our new species. Two morphological features in M. variopinta sp. nov. are rather unusual among scale-worms. One of them is its extremely high level of bilateral asymmetry and antero-posterior variability in elytral distribution and the other one is its elongated, upwardly directed nephridial papillae. The morphology and geographical distribution of the host together with the known characteristics of the symbiotic association have also been highlighted.

“…According to Clark (1956) among one third of commensal Polychaetes reported as many as 100,000 are reef-dwelling species (Spalding et al 2001), and more than 21 Polychaete species found are associated to boring species (Hutchings 1986). Tube dwelling associates bore into the coral matrix and build a calcareous tube on the coral surface (Dai and Yang 1995).…”

Abstract. Sekar V Rajasekaran R, Sachithanandam V, Sankar R, Sridhar R, Kingsley PW. 2016. Species diversity of Polychaete in coral reef ecosystem of Great Nicobar Island,. Crypto fauna inhabiting the shelves of the coral reefs in Great Nicobar Islands are affected by bio-erosion caused by grazing and boring of organisms, hence present study revealed on two major components the opportunistic and true borers. Samples were collected from four stations from three different coral types (live coral, highly degraded & rubble) of the Great Nicobar Islands. Of the total 401 individuals of Polychaetes collected from various sites 8 taxonomic species namely Terebella ehrenbergi, Idanthyrsus pennatus, Lysidice ninetta, L. collaris, Pseudonereis variegata, Perinereis cultrifera, P. nigropunctata, Eurythoe complanata were identified from the aforementioned three coral type sources. Among these P. variegata and L. collaris which accounted for 32.01% and 28.5% respectively, were the most dominant cryptic groups; whereas I. pennatus and T. ehrenbergi were the least records in all three habitats which accounted for 1.75%. In this study, the observations revealed that degraded corals were found in greater abundance than rubble and live corals. The species composition was observed maximum in Laxmi Nagar due to the availability of degraded coral patches than other stations. The study to evaluates the baseline knowledge of the coral inhabiting Polychaete distribution, it would be a pathway for forthcoming researchers on particular group taxonomy, and towards better understanding & utilization of coral reef ecosystem of the Great Nicobar Islands.

“…Some hesionids show commensalistic tendencies (Clark 1956, MacGinitie & MacGinitie 1968), among them P. pugettensis which may either be free living or live associated with echinoderms. Hickok & Davenport (1957) showed that chemical attractants playa major role in host location among commensal individuals of this species.…”
