Actually some of the older females have the fin folded over. The way you can tell that Tili is in the water, is his fluke fin is curved in slightly and his pectoral fins are massive, which makes for the great splashing at the end of the show. As well, he will only do the splash part by himself. Generally when the females do the splash part, there's several females and sometimes the younger ones with them. I've seen as many as 6, and as few as 3 do the ending.
It did seem very very biased. Like they only went there to watch what they did with him. And you may speak to the trainers before/after the shows, but the educators (the ones that stand outside the exhibit) are not part of the same department. And the educators are not always up-to-date on the conditions of each of the animals. They only know the general knowledge/care for the animals. Some of them will go deeper with their information if they choose to.
And as well with anything that happens in the theme park, it stays behind closed doors. They're not allowed to talk about it. There's usually a few general comments that are allowed to be said, but that's it. Those comments that the author spoke of, is nothing different that what was said a year ago about the care/treatment of the whales.
