| Research Abstract |
To clarify mechanism of floating dispersal through asexual reproduction by sponges, we conducted systematic revision of Spheciospongia inconstans (Clionaidae, Hadromerida, Demospongiae), molecular phylogeny of excavating sponge of the family Clionaidae, developmental process of asexual buds, floating/sinking mechanism of buds, and molecular phylogeography of S. inconstans. In consequence, S. inconstans is revealed to be a member of monophyletic clade that has symbiotic zooxanthellae in the family Clionaidae. And S. inconstans should be divided into two species based on morphology of buds and ALG11 sequences. We could not get enough data about developmental process of asexual buds, and floating/sinking mechanism of buds in the fiscal years.
