Progress in taxonomy and symbiotic evolution research of the family Polynoidae from the deep sea
摘要
Abstract
The Polynoidae,one of the most diverse families within the order Phyllodocida of the phylum Annelida,comprises more than 160 genera and 20 subfamilies,with approximately 900 species.It represents a dominant component of deep-sea macrobenthic communities,exhibiting remarkable species richness in both chemosynthetic and typical sedimentary environments,with estimates suggesting that up to 50%of collected specimens could rep-resent novel species.Polynoids also engage in widespread symbiotic relationships with corals,sponges,and other marine organisms.Taxonomic studies of the Polynoidae have evolved over a long period.Initially,higher-rank classifications(e.g.,subfamilies and genera)relied heavily on morphological characteristics,which are often sub-jective,with many groups lacking phylogenetic validation.In recent years,molecular phylogeny has enabled the reclassification of certain groups;for instance,the Macellicephalinae subfamily now incorporates several previous-ly distinct subfamilies isolated from the deep sea.However,the monophyly of certain groups,such as the Poly-noinae subfamily,remains uncertain.Therefore,integrating morphological and molecular data is essential to estab-lish a more realistic and robust classification system.Symbiosis,a key ecological trait of polynoids,encompasses a range of interactions,including parasitism,commensalism,and mutualism.These interactions may have driven the co-evolution of polynoids and their hosts,as well as the development of adaptive features(e.g.,hook-shaped chae-tae).Despite their ecological importance,the evolutionary mechanisms underlying such symbiotic relation-ships—including host choice and adaptive radiation—remain poorly understood.As model polychaetes for studying deep-sea adaptability,further phylogenetic and ecological research,supported by comprehensive datasets,is essen-tial to advance our understanding of deep-sea biodiversity and its associated evolutionary processes.关键词
