Project Description

During a deep dive I saw a large cloud sponge (Aphrocallistes vastus) with a decorated warbonnet peeking out of one of the openings.  The cloud sponge is a white or yellowish deep water sponge with a structure that provides many hiding places for a variety of fish and invertebrates to live.  Some of the projections have a hole (osculum) at the end which is where this fish decided to make its home.  These sponges are huge and can reach sizes of around 10 feet (3 m) across and vertically.  Cloud sponges have a range that includes Siberia, as well as northern Alaska to northern Mexico.
