St. Louis has one of these touch pools. But it's under an outdoor pavilion, so they have to ship the animals back down to Florida every fall, then return them in the spring. That must be incredibly stressful for them; the zoo really should invest in making the attraction indoors. The species are usually cownose rays, southern stingrays, white-spotted bamboo sharks, brown-banded bamboo sharks, and bonnethead sharks. It's an up-charge attraction, and honestly not worth the cost.
Sounds like a lot of extra expense, hassle, and stress on the animals! They don't have an indoor holding tank for colder months?
