This uniquely molluscan structure is formed in the blind end of the radular sac by specialized cells (membranoblasts and odontoblasts). Secretion type, and the number and shape of the odontoblasts that form each tooth characterize the mode of radula formation. These characteristics vary in different groups of gastropods. Elucidation of this diversity is key to identifying the main patterns of radula formation in Gastropoda. Of particular interest would be a phylogenetically closely related group that is characterized by high variability of the radula. One such group is the large monophyletic superfamily Conoidea, the radula of which is highly variable and may consist of the radular membrane with five teeth per row, or the radular membrane with only two or three teeth per row, or even just two harpoon‐like teeth per row without a radular membrane. We studied the radulae of two species of Conoidea (<i>Clavus maestratii</i> Kilburn, Fedosov &amp; Kantor, 2014 [Drilliidae] and, <i>Lophiotoma acuta</i> (Perry, 1811) [Turridae]) using light and electron microscopy. Based on these data and previous studies, we identify the general patterns of the radula formation for all Conoidea: the dorsolateral position of two groups of odontoblasts, uniform size, and shape of odontoblasts, folding of the radula in the radular sac regardless of the radula configuration. The morphology of the subradular epithelium is most likely adaptive to the radula type.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Radula formation in two species of Conoidea (Gastropoda)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-23 01:32:07.386326","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-12-18","DateCreate":"2020-12-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000563881800001","VABBcode":null,"OpenAcc":0,"DOI":"10.1002/jmor.21250"},"refs":null,"anarec":{"AnaID":332262,"PubliDate":2020,"Pagination":"1328-1350","XtraPublOfAnaID":null,"ISBN":null,"Volume":"281","Issue":"10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43085,"SerRR":"Journal of Morphology.
