They are inhabited by many invertebrates and vertebrates which have developed morphological and physiological adaptations to sustain life under these particular conditions. Sandy habitats exhibit three potential constraints: abrasion, hypoxia and mechanical resistance. Here, three teleost species living in sandy environments were investigated: <i>Ammodytes tobianus</i> (Ammodytidae), <i>Gorgasia preclara</i> and <i>Heteroconger hassi</i> (Congridae). These teleost fishes were studied for their integument and muscular systems, which are potentially subject to sand abrasion and hypoxia, respectively. Based on histochemistry and transmission electron microscopy, we found the complex mucus system of <i>G. preclara</i> and <i>H. hassi</i> consists of two types of goblet cells and one type of sacciform cell. The secretions of both species are made of complex polysaccharides. In contrast, the scaly integument of <i>A. tobianus</i> has only a few goblet cells and no sacciform cells. We also highlighted, by immunohistochemistry, that the epidermal cell proliferation was much higher for this latter species, potentially resulting from the high rate of sand abrasion when <i>A. tobianus</i> buries itself quickly in the substrate. For all species, the major muscle fibre type was revealed by histoenzymology and corresponds to fast glycolytic fibres followed by intermediate fibres with slow fibres in the lowest proportion. <i>Ammodytes tobianus</i> possesses the highest fast fibre proportion (about 87% for <i>A. tobianus</i> and 75–78% for both garden eels). Our results provide new insights into the previously poorly studied teleost species, such as <i>G. preclara</i>, and allow us to highlight the complex skin histology of both garden eel species. Furthermore, the previously unknown muscle typing of these three species was determined.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Cytological analysis of integumentary and muscular adaptations in three sand-dwelling marine teleosts, <i>Ammodytes tobianus</i> (Ammodytidae), <i>Gorgasia preclara</i> (Congridae) and <i>Heteroconger hassi</i> (Congridae) (Teleostei; Actinopterygii)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-13 01:31:48.449743","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"goblet cells; histoenzymology; muscle fibres; teleost; sand","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-05-28","DateCreate":"2021-05-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000560000900001","VABBcode":null,"OpenAcc":1,"Handle":"10.1111/jfb.14472"},"refs":null,"anarec":{"AnaID":337720,"PubliDate":2020,"Pagination":"1097-1112","XtraPublOfAnaID":null,"ISBN":null,"Volume":"97","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43231,"SerRR":"Journal of Fish Biology.
