Notes: Excavating sponge. Sparse, rather cryptic papillae; it was revealed to us when collecting another excavating sponge (Cliona aprica Pang, 1973, right side of photo) as a deep blue excavating tissue (center of photo). C. schmidti was originally described from the Mediterranean Sea. It remains to be determined if W. Atlantic populations are conspecific or different.
