1-Fu Chung, Yen-Ming Huang, Tsung-Han Lee, and Li-Lian Liu (2010) Reproduction of the bath sponge Spongia ceylonensis (Dictyoceratida: Spongiidae) from Penghu, Taiwan. Zoological Studies 49(5): 601-607. The reproductive cycle of the bath sponge Spongia ceylonensis Dendy, 1905 was studied over a period of 1.5 yr in the intertidal zone at Penghu, Taiwan. Results indicate that S. ceylonensis is gonochoric and viviparous. Early-stage oocytes were first observed in Mar. in the mesohyl. Embryos and larvae were found to be gathering in the vicinity of the aquiferous canals from Apr. to Sept. Their sizes ranged from 346.0 +/- 57.0 to 395.6 +/- 51.2 mu m, and the mean number of embryos/larvae per mm(3) of tissue varied from 2.7 to 10.7. The larvae belong to the parenchymella type and have a black pigmented ring with long flagella surrounding their anterior. The reproductive period of S. ceylonensis generally coincided with an increase in water temperature, and it remained active in the temperature range of 19-28 degrees C.
