Ripley’s aquarium of Canada has already sold out of its diving with sharks experience, but is taking bookings for next year.

The toronto-based visitor attraction is offering 30-minute guided SCUBA dives through Dangerous Lagoon every Wednesday. Guests will be underwater with sawfish, sharks, turtles and many types of fish.

The two-person experience, which is for certified divers ready to pay CA$250 (US$194, €171, £149), includes backstage tour and photos, a selection of souvenirs and admission to the aquarium.

Dangerous Lagoon is the attraction’s largest tank – with a visitor tunnel the length of a football field, and filled with weird and wonderful sea creatures, including the Pacific sea nettle jelly fish.

As Canada’s largest indoor aquarium, Ripley’s also boasts the biggest shark collection in North America.

Attractions operator Ripley Entertainment opened the CA$130m (US$101m, €89m, £77m) aquarium in Toronto, Ontario, in 2013. It was the third in Ripley's portfolio of marine attractions, following previous openings in Myrtle Beach, South Carolina, and Gatlinburg, Tennessee.
