RESUMO
One out of 45 [2.2%] Orange-spotted trevally, Carangoides bayad [Carangidae], collected off the coast of Egypt in the Red Sea was naturally infected with juveniles of a species of Anisakis [Anisakidae]. Most of the juveniles were found free in the body cavity and unencapsulated on the surface of the liver. The morphology of juveniles was studied using both light microscopy and SEM. The anterior extremity of larvae had a circle of 4 papillae; the characteristic boring tooth, and lateral amphids arranged around a triangular mouth; a cylindrical, esophagus that is light colored with muscular and ven-tricular portions; colorless excretory canals; excretory pore situated just behind the boring tooth. The cuticular surface of the entire body except the cephalic region was striated with discontinuous, undulating longitudinal bands and transverse striations. The posterior extremity was rounded with a distinct mucron. The external morphological features of the juveniles were compared to the previous described genera and species in family Anisakidae harboring the Red Sea fishes
