How old is Spong Bab actually ??

[@Flirtz420]

How do they get their silica?
By filter feeding or like roots digging into the ground?

[@Flirtz420]

Or also by feeding on small silica shelled creatures like diatoms/ dinophyceae/dinoflagellates/etc?

[@OutofPlaceZoologist]

@@Flirtz420 It is by filtering water. Seawater contains dissolved silica

Is it edible?

[@OutofPlaceZoologist]

Some animals do eat them so technically yes, but i would not recommend doing so if you are a human
