Mostly roundish, but not quite that of a circle nor an oval.
A sponge has an asymmetrical symmetry. So they don't have a definite shape.
Sponge is a solid as it has a fixed shape
The sponge is considered to be asymmetrical because it is not a perfect shape, and it is generally an off shape.
It changes shape because the water which absorbes into the sponge makes the sponge ore spongey to be squashed and moveable.

No, sponge is not considered an elastic material. Elastic materials have the ability to return to their original shape after being stretched or compressed, while sponge will deform and retain its new shape.
To create a sponge mold for a specific project, you can start by selecting a sponge that is the size and shape you need. Then, press the sponge into a mold-making material like silicone putty to create a mold of the sponge. Allow the mold to set and then carefully remove the sponge to reveal the mold. You can now use this mold to replicate the sponge shape for your project.

To change the shape of a sponge, I first soaked it in water to make it more pliable. Then, I carefully cut and molded the sponge into the desired shape using scissors or a knife. After shaping, I allowed it to dry in its new form, ensuring it retained the new shape once it was dry. Finally, I could use it for various purposes, such as cleaning or crafting, depending on the shape I created.
A sea sponge has no specific shape(each one differs depending on how the sponge grows, which depends on environmental and genetic factors). It grows as a filter organism, taking in nutrient-rich water and expelling water with all or most of the nutrients removed. An artificial sponge can be just about any shape or size, depending on what the manufacturer wishes for it to be like.
It is round and absolutely delicious :)
Rubber is typically more elastic than sponge due to its ability to stretch and return to its original shape. Sponge, on the other hand, is more compressible and less likely to return to its original shape once compressed. The elasticity of rubber allows it to be used in applications where stretch and flexibility are required, while sponge's compressibility is useful in providing cushioning and absorbing impacts.
