ABSTRACT
The morphology of the gastrointestinal tract of adult Nile perch was described using standard SEM procedures. Investigations revealed the presence of cardiform teeth in the oral cavity, goblet cells and finger print-like microridges on the hard palate and oesophagus lumenal surface. Elaborate patterns and bacterial cells were observed on the stomach lumenal surface and intense foldings in the intestinal region. These observations provide a better understanding of the morphology of the gut in Nile perch and how it is suited for its digestive function.
RESUMEN
El objetivo fue describir la morfología del tracto gastrointestinal de la perca del Nilo adulta mediante microscopía electrónica de barrido estándar. La investigación reveló la presencia de dientes cardiformes en la cavidad oral, células caliciformes y microcrestas como huellas digitales en el paladar duro y la superficie luminal del esófago. Se observaron patrones elaborados, así como bacterias en la superficie luminal del estómago, y plegamientos marcados en la región intestinal. Estas observaciones proporcionan una mejor comprensión de la morfología del intestino de la perca del Nilo y como se adapta para su función digestiva.
