Sponge Spawning

Both brooding and broadcasting reproductive strategies are found in sponges (Porifera). Synchronicity in timing release of gametes has been shown in several Caribbean sponges (Hoppe, 1988). However, regulatory aspects of reproduction in sponges are poorly known (Bergquist 1978). The following footage shows a broadcasting spawning event of the sponge genus, Xestospongia spp. Lunar phase and warmer water temperatures are correlated with the spawning event of these species (Fremont et al. 1994).
