How exactly are the legs lost? (Spoilers)
We see her in the water bleeding heavily and can assume the damage from the destroyed stage may have been so severe that her legs had to be amputated, but later in one of her dreams presumably about the accident we see the orcas toothy open mouth and so I submit that maybe we are being led to believe the whale may have taken a bite?
I have found there have been a shocking number or attacks by captive orcas and more than a few deaths in reality so this is entirely plausible.

I don't really want to hear from the animal rights activists here, if you really cared you would put more effort into it than pathetic guilt trips on internet boards. If it isn't worth risking your life for what you believe, you don't believe with all you are. I would simply like to hear your take on how the director wanted us to believe she lost her legs. If the animal ate them it would add a much larger dimension to her recovery and state of mind.
Truly a beautiful movie shot in a beautiful location. I will not die a happy man until I get to see France. And Spain, India, the Netherlands, and Angkor Wat.
