Animals were maintained in a circulating natural sea water system and fed with <i>Artemia salina</i> nauplii. After a period of acclimation, they were individually isolated, deprived of food for 24 h and submitted to controlled feeding experiments. The absorption develop in the intestinal absorptive cells (A-cells) 5 min after the ingestion of prey and consist in the formation of endocytotic vesicles and endosome-like vacuoles. During the following steps up to 10 h, a second type of digestive vacuole containing electron-dense material, and probably corresponding to a lysosome-like compartment, appears. Throughout this time, the vacuoles progressively arrange in columns, the youngest at the top and the oldest at the bottom of the A-cells. In addition, large lipid inclusions appear in the apical cytoplasm. The ultrastructural changes of the intestinal secretory cells (S-cells) is less marked, but the number of granules largely diminishes during the first 30 min after the ingestion of prey. In starved specimens, major changes in A-cells occur between the sixth and tenth day of starvation and consist in the increase of endosome-like vacuoles. Lysosome-like vacuoles containing dense material are not observed. At the same time, necrosis features are evident in S-cells. After 30 days of starvation, necrosis features are observed in the totality of the intestinal epithelium and the specimens die few days later.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Changes in the structure and ultrastructure of the intestine of <i>Spadella cephaloptera</i> (Chaetognatha) during feeding and starvation experiments","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:06.249758","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2003-05-19","DateCreate":"2003-05-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000089780300001","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0022-0981(00)00228-8"},"refs":null,"anarec":{"AnaID":34909,"PubliDate":2000,"Pagination":"1-15","XtraPublOfAnaID":null,"ISBN":null,"Volume":"253","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43229,"SerRR":"Journal of Experimental Marine Biology and Ecology.
