Aplysia oculifera is an endemic sea hare that inhabits the Egyptian coast of the Red Sea. We describe the reproductive system of this species for the first time. It is composed of an ovotestis, small hermaphroditic duct, nidamental glandular complex, large hermaphroditic duct, gametolytic gland, external seminal groove and cephalic penis. The folli...

Three pleurobranch species; Berthellina citrina (Ruppel and Leuckart, 1828), Pleurobranchus grandis (Pease, 1868) and Pleurobranchus albiguttatus (Bergh, 1905) were collected from seven sites in the upper intertidal zone, on the North Western Coast of the Red Sea; Egypt. They inhabit the lower surfaces of medium sized stones in pools containing wat...

This study gives highlights on the biodiversity of spiders in an olive trees orchard, a lemon trees orchard, and webs of Cyrtophora citricola at Jazirat Shandweel District, Sohag Governorate, Egypt. In addition, it gives a preliminary list of spiders based on the main taxonomic characters. The sampling was carried out weekly or monthly during the p...

Abstract: Spiders have an important role in the agroecosystems. They are effective in suppressing the pest populations as biological controllers. This study aimed to study the abundance, temporal distribution and diversity of spiders in an agriculture research site at Jazirat Shandweel, Sohag District, Sohag Governorate, Egypt. The sampling was car...

Berthellina citrina (Rüppell and Leuckart, 1828) is a common Pleurobranchid gastropod in the intertidal area of the Red Sea. It has distinct color pattern variation from pale yellow, orange to red. The present study aimed to evaluate whether the variation of these color patterns are due to polymorphism, or may be speciation. Anatomically, the three...
