The ancient cloud sponges on this deep water reef in Howe Sound British Columbia is currently being promoted as an ideal spot to put a Marine Sanctuary. This cloud sponge bioherm is located in the southernmost fiord in Canada and it provides ideal habitat for juvenile fish. These cloud sponge bioherms are thousands of years old and are amazing dive sites. A bioherm is a term used where the new sponges grow on the old dead ones. The combination of depth and the fragility of the sponges dictate that any divers must have the ability to keep off of the bottom during their dives. The top of this particular reef starts at 33 meters and goes down hundreds of meters off the sides.
