Átl’ḵa7tsem / Howe Sound Glass Sponge Reef Wildlife

The glass sponge reefs of Átl’ḵa7tsem / Howe Sound are biodiversity hotspots, providing refuge and nursery grounds for numerous marine species from economically important rockfish and spot prawns to sea stars and sea slugs. They are like apartment buildings rising from the flat, muddy sea floor. Check out the wonderful wildlife that have been recorded around glass sponge reefs and call them home.
