Sponges are not one sex, but rather both as needed. This is called a hermaphrodite and it allows the sponge to fertilize eggs. When the baby sponges are released through the oscula they float in the water for several days. They look like plankton, but they attach themselves to the first hard surface they find. Then, they begin growing to become adult size sponges.
^ Was a great answer but didn't really answer the question. Yes, Sponges are hermaphroditic and they contain both male and female gametes, however, as the water passes through the sponge, the sponge releases it's sperm in hopes that it would enter another sponge and then it will find it's way into the egg.
it is either sexual or asexual reproduction. Sexual reproduction is internal.
Mostly external,some species external fertilization .
They have external fertilization
i believe they use decomposed vaginal discharge, I'm not sure tho but i see to remember bear grylls mentioning it went he used natural sponges to bathe himself and then proceeded to eat the sponges and recount a story from his honeymoon which ended "...and that's where these sponges came from". <3
internal fertilization
depends on which kind!
sponges are hermaphrodites. Sperm and ova derived from archeocytes or choanocytes which undergo gametogenesis. Cross fertilization and internal fertilization is taken place.
There are many types of sponges you can use for cleaning. Examples of these are cellulose sponges, abrasive sponges, natural sponges, and dry sponges. The best one would depend on the cleaning surface. It is best to use soft sponges such as the natural sponge to clean fragile surfaces. To clean rough surfaces an abrasive sponge would do the trick.

In vivo fertilization
Locusts use internal fertilization for reproduction. This is when the male locust actively copulates with the female to produce the fertilized egg.
