Glass sponge reefs are unique to the coast of British Columbia, Canada. They represent a living window into the past where sponge reefs once dominated the Jurassic, but disappeared after the Cretaceous.

Today, reefs create habitat for a diverse community of other animals, several of which are commercially important (crustaceans and fish).

Unfortunately, these reefs are not federally protected as marine protected areas. Some reefs, 9000-years old, could potentially be destroyed by fishing activity that frequently occurs on the Pacific coast of Canada.
