Morphological study of the asymmetrical buccal cavity of the flatfish common solea (Solea solea) and its relation to the type of feeding

Abstract

Teeth in the floor of the buccal cavity and taste buds can be considered adaptive changes of the oral cavity related to the feeding habits and was a source to identify new and better methods of nutrition in aquaculture of Solea solea.

The microstructure of buccal cavity and alimentary canal of Siganus rivulatus: Scanning electron microscope study

“…Various functions were reported for microridges as secretion, absorption, mechanical protection, and flexibility, and mucous secretions holding (Baaoom, ; Harabawy et al, ). The mucous holding on the surface of the cells help to reserve surface area for stretching or distortion, and spreading the mucous outside the goblet cells (El Bakary, , ; Mittal, ; Yashpal et al, ). The distribution of the microridges above epithelium of the lingual body has been identified as structures that increase the persistence of mucus on the epithelium (Jackowiak and Ludwig, ).…”

“…The mucous holding on the surface of the cells help to reserve surface area for stretching or distortion, and spreading the mucous outside the goblet cells (El Bakary, 2011, 2014Mittal, 2004;Yashpal et al, 2006). The distribution of the microridges above epithelium of the lingual body has been identified as structures that increase the persistence of mucus on the epithelium (Jackowiak and Ludwig, 2008).…”

“…The shapes of mouth and oral cavitiesy of fishes are good clue to indicate what fish eat. Buccal or orophryngeal cavity shows structural adaptability and great plasticity for eating different food items (Abbate et al, ; Abbate, Guerrera, Montalbano, Ciriaco, & Germanà, ; Abbate, Guerrera, Montalbano, de Carlos, et al, ; Baaoom, ; El Bakary, ; El Bakary, ; Harabawy, Mekkawy, Mahmoud, Abdel‐Rahman, & Khidr, ; Horn, ; Kapoor & Khanna, ; Kapoor, Smit, & Verighina, ; Levanti et al, ). The alimentary canal morphology in fishes usually shows characteristic variations in relation to diet, habit of feeding, phylogeny, shape of body, and characters that show functional differentiation (Abaurrea, Nuñez, & Ostos, ; Anderson, ; Kapoor et al, ; Noaillac‐Depeyre & Gas, ).…”

Morphology of the Atlantic salmon (Salmo salar)tongue

“…It is well known that feeding in captivity should cause adaptation and modifications of the morphological characteristics of the oral cavity, especially of tongue and teeth. Morphological data, particularly on tongue of different species of fish, are present in literature (Abbate et al., 2006, 2017; Abbate, Guerrera, Montalbano, Ciriaco, & Germanà, 2012; Abbate, Guerrera, Montalbano, De Carlos, et al, 2012; Collar, O'Meara, Wainwright, & Near, 2009; Dos Santos, Arantes, Santiago, & Santos, 2015; El Bakary, 2014; Elgendy, Alsafy, & Tanekhy, 2016; Guerrera et al., 2015; Ikpegbu, Ibe, & Nlebedum, 2019; Levanti et al., 2017; Mahmoud, Essa, & Sayed, 2016; Montalbano et al, 2016; Price et al., 2010; Sadeghinezhad, Rahmati‐Holasoo, Fayyaz, & Zargar, 2015; Yashpal, Kumari, Mittal, & Mittal, 2009). Nevertheless, recent data regarding the tongue anatomy in upper vertebrates are significative and could be very important in comparative anatomy (Abbate et al., 2008, 2009, ; Emura, 2016a, 2016b, 2016c, 2017, 2018a, 2018b, 2018c, 2018d; Emura & Sugiyama, 2016; Erdogan & Alan, 2012; Erdoğan & Iwasaki, 2014; Erdoğan, Lima, & Pérez, 2016; Erdoğan & Sağsöz, 2018; Erdoğan, Villar Arias, & Pérez, 2016; Erdoğan, Villar, König, & Pérez, 2018; Herrel, Redding, Meyers, & Nishikawa, 2014; Jackowiak, Skieresz‐Szewczyk, Godynicki, Iwasaki, & Meyer, 2011; Jackowiak, Skieresz‐Szewczyk, Kwiecińsk, Trzcielińska‐Lorych, & Godynicki, 2010; Sadeghinezhad et al., 2015; Sadeghinezhad, Sheibani, Memarian, & Chiocchetti, 2017; Sadeghinezhad, Tootian, & Javadi, 2018; Skieresz‐Szewczyk, Cornillie, & Jackowiak, 2018; Skieresz‐Szewczyk & Jackowiak, 2016, 2017; Skieresz‐Szewczyk, Jackowiak, & Ratajczak, 2018, 2019).…”

Gross morphology and scanning electron microscopy of the Bagrus Bayad (Forskal, 1775) oropharyngeal cavity with emphasis to teeth‐food adaptation

“…The mouth cavity anatomy of fishes is a good indicator to what a fish eats because it appear a structure adaptability to different food types (El Bakary, 2012, 2014Mahmoud, Essa, & Sayed, 2016).…”
