the sponge absorbs water, and keeps it in. if you rotate or tilt it, the water will move because of gravity.
Sponge bob has nothing to do with it.
Spicules, like our skeleton, give the sponge structure. Without spicules, Sponge Bob would be Sponge Blob.
The spicule in a sponge is its skeleton. It provides strength in the sponge.

First sponge iron must be Roll crusher Next Magnet separation Next Create block sponge iron
Yes, because you can disrupt a whole sponge in the bottom of the see, in a good place without hard currents, and every (in a high percentage) will be an adult sponge.
ostia -spongocoel-osculum
A network of spongin or spicules.
The movement of water provides a simple mechanism for feeding respiration circulation and excretion.
No because it makes filter-feeding impossible for the sponges No because it makes filter-feeding impossible for the sponges
The osculum is an excretory structure in the living sponge, a large opening to the outside through which the current of water exits after passing through the spongocoel. Wastes diffuse into the water and the water exits through the osculum at a velocity of nearly 8.4 cm/second, carrying away with it the sponge's wastes. The size of the osculum is regulated by the myocyte. Its size, in turn, determines the amount of water flowing through the sponge.
