If you’re looking for information on Marineland, you should check out MLCC Slipstreams:
MLCC Slipstreams is your number one site on the net for information on the cetaceans (whales and dolphins) of Marineland located in Niagara Falls Ontario, Canada. Marineland is one of two Marine themed parks in Canada, the other being the Vancouver Aquarium. It is however the only marine park in Canada that holds captive Orcas (also known as Killer Whales).
The site has a lot information about the whales and dolphins, including where they came from and their age. There are also some nice pictures from “back in the day”.
For some reason, some of the pictures aren’t showing up correctly at the moment. The last time I visited the site, everything was fine, so the person who runs the site might be updating things.
