Identification of Morphology of Zeylanicobdella Arugamensis in Tiger Grouper (Epinephelus Fuscoguttatus) Using Scanning Electron Microscope Method in Lampung Bay, Indonesia

This research aims to study the morphology of Zeylanicobdella arugamensis infesting tiger grouper (Epinephelus fuscoguttatus) at Lampung Bay Waters by using scanning electron microscope (SEM). The samples were obtained from body surface fuscoguttatus). has an elongated silindris with sucker in anterior and posterior. Based on results SEM , parasite a length 4 - 4.1 mm width 0.5 suckers gap middle surrounded cuticle projections shaped like flower petals white cilia diameter 0.3 0.4 posterior part 0.9 1.4 where size is larger than sucker. On ventral there transverse segmented coelom which separated cavity. Keywords: Tiger grouper, arugamensis, Scanning Electrone Microscope (SEM), Hirudinea
