“…In the history of marine biology, a sustained interest in the relationships between crinoids and their symbiotic partners has long been evident. Besides studies devoted to single taxonomic groups, investigations of the entire crinoid symbiont community have been conducted in various coastal ecosystems around the world, notably in the Bay of Bengal [13], the Red Sea [9], the Marshall Islands [14], the Maldives Archipelago [15], Hong Kong [16], the Great Barrier Reef [6], Taiwan [17], New Guinea [7], Japan [18], South Africa [19], Vietnam [5,20] and North Sulawesi [21]. Such investigations have consistently emphasized the prevalence of specialized fauna involved in symbiotic associations with crinoids.…”

Crinoids (Echinodermata) exhibit unique morphological and behavioral characteristics that facilitate a wide range of symbiotic relationships with diverse organisms. Our comprehension of their interactions with microscopic copepod crustaceans is, however, still in a nascent and fragmented state. Here, we review and discuss the 166 literature records to date in which a total of 39 copepod species in 6 families have been reported in association with 33 species of the crinoid order Comatulida. Many of these associations have been reported just once. The respective localities cover 5 of the World Ocean’s 12 ecoregions, with a notable concentration of both host and symbiont diversity in the Central and Western Indo-Pacific. In contrast, the documentation of copepod–crinoid associations in the Atlantic appears markedly limited. Copepods have been found predominantly in ectosymbiotic relationships with crinoids, with a lower incidence of endosymbiosis. Copepods of the genera Collocheres Canu, 1893 and Pseudanthessius Claus, 1889 are particularly prominent in the list, and the comatulid family Comatulidae displays the most diverse assortment of copepod associations. The current scope of knowledge encompasses a mere 5% of the potential crinoid host diversity, underscoring the need for more extensive research in this area.

“…Historical examinations within marine biology underscore a sustained interest in the relationships between crinoids and their symbiotic partners. The investigations have been conducted in various coastal ecosystems around the world, with notable studies including those conducted in the Bay of Bengal (Rao, Sowbhagyavathi, 1972), the Red Sea (Fishelson, 1974), the Marshall Islands (Zmarzly, 1984), the Maldives Archipelago (Tchesunov et al, 1989), Hong Kong (Morton and Mladenov, 1992), the Great Barrier Reef (Fabricius and Dale, 1993), Taiwan (Huang et al, 2005), New Guinea (Deheyn et al, 2006), South Africa (Hempson and Griffiths, 2008), Vietnam (Britayev and Mekhova, 2011;Britayev et al, 2016), and North Sulawesi (Virgili et al, 2020). Comprehensive investigations pertaining to this subject have consistently emphasized the prevalence of specialized fauna engaged in symbiotic associations with crinoids.…”

Crinoids (Echinodermata) exhibit unique characteristics that facilitate a wide range of symbiotic relationships with diverse organisms. Nonetheless, the comprehension of their interactions with microscopic copepod crustaceans is still in a nascent and fragmented state. Our analysis identifies 166 instances involving 35 copepod species representing in 6 families in association with 33 species of the Comatulida. The majority of these associations have been singularly reported, with their distribution covering five out of the 12 World Ocean ecoregions. A notable concentration of diversity is observed in the Central and Western Indo-Pacific regions, while documentation of Atlantic copepod-crinoid associations is markedly limited. Copepods are predominantly found in ectosymbiotic relationships, with a lesser incidence of endosymbiotic interactions. Among these, the genus Collocheres and Pseudanthessius emerge as particularly prominent, and the Comasteridae family is distinguished by its diverse copepod associations. While certain copepod families exhibit a specialization towards crinoids, others demonstrate specificity at the species level. The current scope of knowledge encompasses merely 5% of the potential crinoid host diversity, underscoring the critical need for more extensive research in this area.

“…Echinoderms, a well-defined and highly-derived clade of metazoans with approximately 7,000 species, can be found in various habitats ranging from shallow intertidal areas to abyssal depths [13]. Numerous echinoderms have been found with diverse macrosymbiotic organisms, including feather stars (crinoids) [14][15][16], sea cucumbers (reviewed by Martin & Britayev [17]; Purcell et al [18]), sea urchins [15,16,[19][20][21], brittle stars [17], and starfish [17,19], as well as the small crustacean copepod associated with brittle stars [22]. Approximately 1,500 species of starfish live in all marine waters [23], and 48 valid species from 10 families have been recorded in waters around Taiwan [24,25].…”

Macrosymbionts of starfish Echinaster luzonicus (Gray, 1840) in the waters of a volcanic western Pacific island

During an investigation program of faunal diversity in the shallow reef zone of the active volcanic island off northeastern Taiwan in July and September 2020, numerous individuals of the starfish Echinaster luzonicus (Gray, 1840) were found, and some individuals were found with associated symbionts. Starfish sampling in the 150-m coral reef zone was undertaken at a depth of 8 m through scuba diving. For each type of potential macrosymbiont, both the dorsal and ventral sides were carefully examined. The prevalence of macrosymbionts on the starfish E. luzonicus was recorded. The most common symbiotic organism on E. luzonicus was the ectoparasitic snail Melanella martinii (A. Adams in Sowerby, 1854), followed by the pontoniine shrimp Zenopontonia soror (Nobili, 1904) and the rare polychaete scaleworm Asterophilia carlae Hanley, 1989. The prevalence ratio with host E. luzonicus was low and varied by 8.62% and 4.35%, 6.03% and 0%, and 0.86% and 0.72% in July and September 2020 for M. martinii, Z. soror, and A. carlae, respectively. The present study is the first to discover the scaleworm A. carlae as a macrosymbiont of the tropical starfish E. luzonicus, with a widespread distribution, off Taiwan’s northeastern coast, an area influenced by the Kuroshio Current.
