| Abstract | ||
| An acoelan turbellaria “Anaperus trifurcatus” are collected for the first time, from the salt waters of the Bitter lakes of the Suez Canal – Egypt, as the ecological parameters are nearly similar to that existing in shallow sea water of Ghardaqa in the Red sea. These turbellarians are found living around the sea-weeds such as Sargassum vulgare and Cystoseira myrica. It is greenish brown in coloration due to the presence of zooxanthellae symbiotic (brown algae). This animal is related to the genus Anaperus (Graff, 1912) and to the species trifurcatus (Beltagi, S. 1983) as it possesses 2 latero-ventral ciliated sensory pits, triforked posterior end and a well developed nervous system formed of a central brain mass giving rise to 5 pairs of nerve stems, a pair of dorsa-lateral nerve stems, a pair of latero-ventral stems, a pair of ventral nerve stems and a pair of longitudinal postero-dorsal nerve stems. The bursa seminalis is absent and 8 spermballs with their chitinised mouth pieces. | ||
