Interesting little story, have you seen the documentary Blackfish? If you havent you should check it out its very eye opening and I learnt a lot about these animals.
They form very close family bonds and are massively intelligent, what was done to them at seaworld was obscene to say the least.
Good luck with the next part.
I know of it, I can't watch it id be too disturbed. I love marine animals..all animals actually :) Thx for checking out my post @gyro!
