A graphically illustrated glossary of polychaete terminology: invasive species of Sabellidae, Serpulidae and Spionidae

Abstract

A well-illustrated glossary supports the study of polychaete anatomy and systematics, as well as aiding species identiication, a need that emerged within the shipping and aquaculture industries over recent decades. Sabellidae, Serpulidae and Spionidae are polychaete families that most often include species that are translocated globally through ship fouling, ballast water or aquaculture trade. Accurate identiications are crucial since these translocations have signiicant ecological and commercial implications and also for phylogenetic and other biological studies. Using digital illustrations of specimens (deposited predominantly at the Australian Museum in Sydney), a glossary has been developed for these three families with the aim of standardising terminologies. Complete-focus images were generated with Helicon Focus 5.3 Pro software from multiple image layers. The deinitions have been explained speciic to families and illustrated with these images, thus creating the irst comprehensive, digitally illustrated glossary of polychaete terminology.
