The Beluga whale interaction I'll write about on Monday was the same Wild Arctic interaction that SeaWorld sells -- I did it with seven others -- but, again, that was arranged for me through the SeaWorld PR department, so that I could get up-close photography for use on TPI. Since it was an arranged visit, I won't be evaluating or reviewing the interaction, just describing it in first-person detail and showing you the photos.
Let’s keep hoping the Busch Family keeps these beautiful parks.
So, yeah, they pee in the tank. But let's put it this way: the toilet is always flushing.
FWIW, SeaWorld San Diego pulls its tank water from nearby Mission Bay. So it is the only SeaWorld park that's using natural salt water. SeaWorld filters the sea water before putting in the tanks, then again before it is recycled into the bay. Several trainers made a point of saying that the water is cleaner when SeaWorld puts it back in the bay than when SeaWorld takes it out.
