Abstract

This poster describes ascaridid nematode species Dujardinascaris madagascariensis Chabaud et Caballero, 1966, which was obtained by parasitological dissection from the stomach of a perished Nile Crocodile at Lake Turkana. Nematodes have been studied by scanning electron microscope to determine and redescribe their external morphology. For SEM, specimens were prepared by the standard method. Beside classic scanning electron micrographs we used also stereomicrographs for morphologic observations of nematode head structures. Two micrographs taken at moderately different viewing angles were used for the stereoscopic imaging. The optimal angle difference is 4-6 degrees. Obtained images make use of the parallel viewing method or they can be joined into stereoscopic pictures (also known as 3D anaglyphs). Anaglyphs are pictures where the red and blue channels have been split and then reassembled so that the image appears three-dimensional when viewed through 3D glasses with red and blue lenses.
