I was invited on a site tour of Vancouver Aquarium, where I had the opportunity to go behind the scenes. This photo is of Jellyfish being studied, some of them new to the British Columbia coast. Recent studies suggest jellyfish are increasing in most coastal ecosystems. This has impact on pretty much everything that has to do with drawing in water including nuclear plants and fishing. Overfishing and global warming are probably the most important drivers of increased jellyfish.
