Dolphin intelligence experiment

[tsukishima_shizuku]

I read this book in elementary school in the mid-90s in USA and I believe it was fairly newly published at the time. It was a middle-grade chapter book with a blue cover.

I don't remember a lot about it but parts of it were told from the point of view of a dolphin (or some type of cetacean) undergoing intelligence testing. Then at some point the dolphin might have escaped from captivity. That's all I remember...

Anne McCaffrey writes a dolphin book that sounds like this. Dolphins of Pern, I believe. I wouldn't classify it as middle-grade book, although a middle schooler could read it.
