Abstract
AbstractThe Characters of egg capsules which produced by the fresh water snailLymnaeaauricularia were recorded.The results showed thatthe lengthsof the capsules were between4-30 (mm), while the width were between( 1.5– 3.7)(mm), the diameters of the eggs were 8-72 μm and (11- 83)μm for the small dimeter and the larger one, respectively.It is obviously seen that this snail produces 6-116 egg/egg capsule,and there are(7)developmental stages for the embryos hatched to mallsnail resamble their parents, and the incubation period was (10) days.
