Abstract:
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.
摘要:
海百合(棘皮动物)具有独特的形态和行为特征,可促进与多种生物的广泛共生关系。我们对它们与微小co足类甲壳类动物相互作用的理解是,然而,仍然处于新生和支离破碎的状态。这里,我们回顾并讨论了迄今为止的166个文献记录,其中6个科总共有39个co足类物种与海百合科马图利达的33个物种有关。这些协会中的许多协会仅被报道过一次。各自的地区覆盖了世界海洋12个生态区中的5个,在印度洋中部和西部,寄主和共生体多样性明显集中。相比之下,关于大西洋co足类-海百合类动物协会的文献似乎明显有限。已经发现co足类动物主要存在与海百合的外生共生关系,内共生的发生率较低。CollocheresCanu属的co足类,1893年和PseudanthessiusClaus,1889年在榜单中尤为突出,和comatuliid家族comatulidae显示最多样化的co足类协会。目前的知识范围仅包括5%的潜在海百合宿主多样性,强调需要在这一领域进行更广泛的研究。
