Early #sponges were soft https://phys.org/news/2026-01-earth-early-sponges-soft-scientists.html

Independent origins of spicules reconcile paleontological and molecular evidence of sponge evolutionary history https://www.science.org/doi/10.1126/sciadv.adx1754 by Maria Eleonora Rossi et al.

"the first sponges were soft-bodied and lacked mineralized skeletons. That's why we don't see sponge spicules in rocks from around 600 million years ago—there simply weren't any to preserve... spicules evolved independently in different sponge groups"

A collage of four pictures. Three are underwater photos of sponges and the fourth contains electron microscopy pictures of their skeletal structures of various mostly symmetrical shapes.
