| Reproduction Preferences Additional Information | The sperm of sponges are frequently 'broadcast' into the water column. A sponge creates and concentrates the sperm, before expelling it from the excurrent (oscula) pores. The masses of sperms thus released are sometimes so dense that the sponge appears to be smoking. The sperm are then carried by the water current towards another sponge. There, they are captured by the female cells, the choanocytes. Inside the female, the sperm are transported to eggs by special cells. Fertilization occurs, and the resulting [zygotes] [fertilised eggs] develop into [ciliated] larvae. | ||||||||||||||
