osculum and ostia are the holes in the sponge that can be used as mouths
I think they're called Ostia.
ostia -spongocoel-osculum
The sponge works like a chimney. Water rushes in from beneath through ostia and comes out ffrom osculum. This action is continuously controlled by wholly or partially closing the osculum and ostia and varying the beat of the flagella, and the pores may shut if there is a lot of sand in the water before it could block the system.
A sea sponge absorbs water through numerous minute, dermal pores on its body surface known as ostia.
ostia is the inlet into the sponge and osculum is the outlet through which the entered water etc. moves out
tiny "whips" on the cells inside a sponge draw water in through the pores of thesponge. Food is then removed from the water before it leaves through the opening at the top of the sponge .
Ostia may refer to: * Ostia Antica, a township and port of ancient Rome * Ostia(town), a modern township (also called Ostia Lido or Lido di Ostia) on the Tyrrhenian Sea coast, near Rome, Italy. Usually, when modern Roman people say Ostia they refer to the modern town, not the nearby archaeological site. It can also refer to either of two modern districts of Rome: * Ostia(modern district),roughly co-terminous with Ostia (town) * Ostia Antica(district) (originally known as Gregoriopolis)
Small pores of sponges are called ostia through which water enters while a large pore through which water exits is called osculum .
Ostia is just a few kilometers from Rome.
