Massive irregular sponges overgrowing bryozoans. Two specimens (SMF 11783, 11784) were dead when sampled, they mainly consist of skeletal parts, while most of the soft body is missing. The third (SMF 11781) and largest sponge was alive, it has a great amount of soft tissue surrounding the skeleton. Skeleton of thick plumose tracts, splitting towards the surface. Sponge surface smooth with a discrete detachable ectoderm. Ectosomal skeleton forms irregular tangential reticulation. A large amount of foreign material, especially bryozoan colonies, incorporated into the tissue. Color
