Morphology of the Ovotestis of Synaptula hydriformis (Holothuroidea, Apoda): An Evolutionary Model of Oogenesis and the Origin of Egg Polarity in Echinoderms
The viviparous holothuroid Synaptula hydriformis, a simultaneous hermaphrodite, broods its young in the coelom and releases young year round.
