The development of Spongilla lacustris from the oocyte to the free larva (Porifera, Spongillidae)

This paper describes the embryonic development of Spongilla lacustris (Linne 1758) (Spongillidae) from the young oocyte to the free larva. The spongillids are viviparous: that is the development from egg to larva takes place within the tissue of the mother sponge. The parenchymula larva leaves the m...

Zusammenfassung:	This paper describes the embryonic development of Spongilla lacustris (Linne 1758) (Spongillidae) from the young oocyte to the free larva. The spongillids are viviparous: that is the development from egg to larva takes place within the tissue of the mother sponge. The parenchymula larva leaves the mother sponge by way of the excurrent canal system.
