Did you know that glass sponges form reefs the size of cities here in BC? If we were to drain the water from the Strait of Georgia (between the mainland and Vancouver Island, where Bamfield sits), you’d be able to see huge structures built by generations of glass sponges as they grew higher and higher to get into strong water flow. Among other things, the Leys lab–headed by Dr. Sally Leys at the University of Alberta–studies the glass sponge reefs. Student Sameena Sherman put together two videos to introduce the reefs and the animals that live in them. If you haven’t seen the first video, you can find it here. Check out the latest video, Animals of the Reefs, below!
