Abstract
The sandbar shark, Carcharhinus milberti (Müller and Henle) taken from the East China Sea, includes 2 to 10 embryos with an average of 6.0 and a mode of 6.More than 80 % of gravid females contain 5, 6, 7, and 8 embryos.Marked difference cannot be seen in the number of embryos between the left and right uterus.The ratio of males to females in the embryos is about 1: 1 as a whole, although the ratio differs by litter.The length at birth is usually 65 cm to 75 cm in total length.Season of birth is estimated to be between June and July since near full-term embryos appear at that time.The gestation period is guessed to be 10 to 12 months.
