They had the world largest captive breeding colony and now its kind of sad to think theres only Rosie left. Im going to miss her when she goes, shes such a sweetie. I think its for the better that they are being phased out though. Breeding is not needed anymore as there not endangered anymore. The exhibit they currently live in is a great size but its beginning to show its age and the water is fresh which is bad for there eyes. It would cost millions to create a new exhibit or to renovate this one so in the long run, as sad as it will be to see them go, i think it might be for the better. I really wish they would have included at least one pinniped species into Tundra Trek but again, its about the cost
