ABSTRACTSummary The zebrafish is a common model for developmental studies including those regarding tooth, palate and tongue. Nevertheless, little information is available about the morphology of the oral cavity in this teleost, especially in adult animals. In this study we used light, scanning and transmission electron microscopy to describe in detail the morphology of the oral cavity of adult zebrafish. The oral cavity could be divided into three different zones: the outer containing the lips, the intermediate corresponding to the internal valves and the internal that corresponds to the tongue. In the upper and lower intermediate zones, there were semilunar shaped valves, more prominent in the upper part. The internal lower zones correspond to the palate and the tongue, which is an individualized structure filled with numerous transversal ridges. Both the intermediate and internal zones were covered by a stratified epithelium containing numerous mucous and rodlet cells. Present data provide the first description of the morphology and structure of the oral cavity in the adult zebrafish and might serve as a baseline for developmental studies of the oral cavity using this teleost as a model.
