Underwater marvels from around the world are divided into 10 galleries at Canada’s largest aquarium. The Great Lakes’ deep-dwelling denizens get their due in the first exhibit where prehistoric-looking paddlefish and sturgeon prowl. After being impressed by the macrofauna that lives in Lake Ontario, check out the crazy Canadian creatures that call the Atlantic and Pacific oceans home. The Giant Pacific Octopus isn’t quite kraken-sized, but he’s impressive nonetheless, as are the extremely rare electric blue lobsters. Then hop over to the other side of the world (minus the jet lag), and get lost among the Indo-Pacific coral reef residents. The Rainbow Reef gallery is the aquarium’s most diverse exhibit, with over 100 species of colorful fish with funky names like the unicorn surgeon, Picasso triggerfish, and harlequin tuskfish. From there, a moving sidewalk carries you through the Dangerous Lagoon, a 90m (295-ft.) underwater tunnel where green morays, giant groupers, sharks, and sea turtles sail past. Other highlights include Planet Jellies, an entire hall dedicated to stinging plankton, and the Discovery Centre, where budding marine biologists can crawl through underwater tunnels into transparent viewing bubbles that put you smack-dab in the middle of a clownfish school—it’s about as close as you can get to hanging out with Nemo and his pals without a SCUBA certification.
