Given that:
Sponges do not possess any structures that can be considered organs. For instance, sponges do not have stomachs or kidneys. Instead, sponge cells of various types are responsible for bodily functions, the day-to-day activities that sustain life.
Sponges are primarily marine, mostly in shallower coastal waters, although fresh water sponges also exist.
Sponges are sessile and attached to either the substrate or submerged objects- occasionally on other animals such as crabs
Sponges have 4 very loosely differentiated cells:
* Pinacocytes- outer cells covering sponge; equivalent of epidermis, “skin cells”
* Porococytes- cells which line the pores of the sponge; through which water is drawn
* Choanocytes- similar to choanoflagellates; collared cells with flagella which create water current and collect food matter or sticky contractile collar.
* Amoebocytes- amoeba-like cells found throughout the sponge; store, digest and transport food, excrete wastes, secrete skeleton and also may give rise to buds in asexual reproduction;
Conclusion:
Some species of sponges are sexual, but it appears that the sqaurepantzia variety is asexual, having both egg and spermatic cells, and since this particular variety has no specific gender, or both genders if you will, homosexuality has no meaning in this special context.
