Neanthes goodayi sp. nov. (annelida, nereididae), a remarkable new annelid species living inside deep-sea polymetallic nodules

A new species of abyssal Neanthes Kinberg, 1865, N. goodayi sp. nov., is described from the Clarion-Clipperton Zone in the central Pacific Ocean, a region targeted for seabed mineral exploration for polymetallic nodules. It is a relatively large animal found living inside polymetallic nodules and in xenophyophores (giant Foraminifera) growing on nodules, highlighting the importance of the mineral resource itself as a distinct microhabitat. Neanthes goodayi sp. nov. can be distinguished from its congeners primarily by its distinctive, enlarged anterior pair of eyes in addition to characters of the head, pharynx and parapodia. Widespread, abundant, and easily recognisable, N. goodayi sp. nov. is also considered to be a suitable candidate as a potential indicator taxon for future monitoring of the impacts of seabed mining.

Abstract

A new species of abyssal Neanthes Kinberg, 1865, N. goodayi sp. nov., is described from the Clarion-Clipperton Zone in the central Pacific Ocean, a region targeted for seabed mineral exploration for polymetallic nodules. It is a relatively large animal found living inside polymetallic nodules and in xenophyophores (giant Foraminifera) growing on nodules, highlighting the importance of the mineral resource itself as a distinct microhabitat. Neanthes goodayi sp. nov. can be distinguished from its congeners primarily by its distinctive, enlarged anterior pair of eyes in addition to characters of the head, pharynx and parapodia. Widespread, abundant, and easily recognisable, N. goodayi sp. nov. is also considered to be a suitable candidate as a potential indicator taxon for future monitoring of the impacts of seabed mining.

More information

Published date: 14 July 2021
Additional Information: Funding Information: The UK Seabed Resources ABYSSLINE (ABYSSal baseLINE) environmental surveys were supported by a collaborative partnership between six non-profit global academic research institutes (University of Hawaii at Manoa, Natural History Museum, NORCE Norwegian Research Centre, National Oceanography Centre, Senckenberg Institute and Heriot-Watt University) and through an arrangement with UKSRL (UK Seabed Resources Ltd.). Additional support was provided by the Swedish research council FORMAS (TGD). We acknowledge Madeleine Brasier from the Natural History Museum team and Swee Cheng Lim from the National University of Singapore for support with sorting and sampling on board ship, and Chief Scientist Craig R. Smith for organizing the project and leading the sampling program. We also acknowledge the expert support from the Senckenberg Institute team in the deployment and recovery of successful Brenke epibenthic sledge samples. This study was made possible only by the dedicated help of the entire scientific party, the masters and crew of the RV Melville during the first cruise of the ABYSSLINE project in October 2013 and the masters and crew of the RV Thomas G. Thompson during the second ABYSSLINE cruise in February and March 2015. We sincerely thank reviewers for their effort in providing detailed comments and suggestions, which helped improve and clarify this manuscript. RD would like to thank and acknowledge support from the NERC INSPIRE DTP for the time needed to complete the manuscript. Thank you also to Emma Sherlock, Senior Curator of Annelida, Jackie Mackenzie-Dodds at the Molecular Collection Facility, and Harry Rousham and Robyn Fryer, Consultancy Group, all at the Natural History Museum.
