Thank you, Mr. Chair.
Thank you both for being here, and Dr. Visser. Some of us were a little late. I didn't get to hear your opening comments because we were listening to comments of our Prime Minister in the House on the issues in New Zealand.
I remember when we had our first killer whales, our first orcas, in the Vancouver Aquarium. What we noticed at the time was the dorsal fin. It is usually straight up and down, very rigid in the wild. It was curved over.
Dr. Visser, do we know why that happens?
