The study was carried out in Port Blair Bay, Andaman Islands. Sampling for biological-chemical parameters was carried out from eight sampling stations during southwest monsoon (August). Swarming of <i>C. acicula</i> was observed in the outer region of Port Blair Bay. The pteropod population was found maximum in Aberdeen Bay with 1765 Nos./m<sup>3</sup> during the low-tide. Pteropod was the dominant zooplankton group in two stations. The water column was well mixed with temperature ranging from 28.1 to 28.7°C with a vertical gradient of 0.0–0.3°C and salinity ranging from 30.27 to 32.93 PSU with a vertical gradient of 0.1–0.3 PSU. In the zooplankton sample, almost all the pteropod shells were empty and there was no trace of organisms that escaped/released from the shell. From the observation of this study and other global studies, we hypothesize that this large number of <i>C. acicula</i> may be due to the aggregation of shells from nearby areas by oceanographic processes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Swarming of holoplanktonic gastropod (<i>Creseis acicula</i> Rang, 1828) in Andaman Island during southwest monsoon, possible reasons and its global swarming records","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-07-15 01:32:28.160701","timezone_type":1,"timezone":"+02:00"},"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-03-04","DateCreate":"2025-03-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1093/plankt/fbaf005"},"refs":null,"anarec":{"AnaID":405930,"PubliDate":2025,"Pagination":"fbaf005","XtraPublOfAnaID":null,"ISBN":null,"Volume":"47","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43255,"SerRR":"Journal of Plankton Research.
