10.2.1 Female Reproductive System

Female chondrichthyan fishes have a pair of reproductive tracts and either paired ovaries or a predominant single ovary where the second is vestigial or absent. Each reproductive tract typically consists of a funnel-shaped ostium, anterior oviduct, oviducal gland, isthmus for some species, uterus, and cervix, leading posteriorly to the urogenital sinus common to both tracts and opening into the cloaca (Fig. 10.1).
