My real answer is turtle at my Cambodian friend's house in high school. I was at her house one day, she didn't have any pets but I kept hearing this scratching noise. I asked her What the Fork! it was and she opened a cooler and there were turtles in there and she said her mom was going to make soup with them. So of course I had to try it.
I also have had sting ray ceviche in Ecuador as well as guinea pig.
