We describe a new doliolid that has successfully made the transition into deep water. Nine specimens of <em>Pseudusabostigrinus</em> have been found at depths between 1164 and 1890 m in three distinct regions of the eastern North Pacific. This new thaliacean has exchanged the typical doliolid body plan for one resembling a craspedote hydromedusa. This adaptation allows it to collect sinking particles by simply directing its large buccal opening upward. The development of a hydromedusa-like velum allows it to trap zooplankton prey and to propel itself with considerable force and control. While carnivory is not unknown in tunicates, this is the first report of a carnivorous doliolid. The endostyle of <em>P.bostigrinus</em> is greatly reduced, there are no ciliated bands, and there is no spiral gland; all evidence that mucus feeding filters have been abandoned by this species. Anatomy, diet, behaviour, and habitat distinguish this doliolid from all others described to date.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Adaptations for living deep: a new bathypelagic doliolid, from the eastern North Pacific","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:11.218951","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2020-10-07","DateCreate":"2005-07-26","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000230996200016","VABBcode":null,"OpenAcc":0,"DOI":"10.1017/S0025315405011525"},"refs":null,"anarec":{"AnaID":74961,"PubliDate":2005,"Pagination":"595-602","XtraPublOfAnaID":null,"ISBN":null,"Volume":"85","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43277,"SerRR":"Journal of the Marine Biological Association of the United Kingdom.
