Stingray Ahimsa:
https://us.yahoo.com/news/stingray-impales-womans-back-missing-015512418.htmlA Florida woman is recovering after a stingray impaled her back and came within an inch of her lung with one of its barbs.
Kristie Cataffo-O’Brien had to undergo surgery to remove the stinger, spent a week in the hospital and still finds it incredibly painful to move her right arm.

Stingrays are shy and gentle, but they have long, thin tails equipped with up to three barbed, venomous spinal blades, which they use in self-defense when they feel threatened
...
Steve Irwin, the TV personality known as the “Crocodile Hunter,” died in 2006 when a stingray he was swimming with pierced his heart with its poisonous spine.
Imagine: Irwin might still be around today had his victim not retaliated! Think about how many more victims of Irwin there would have been! This is how valuable Ahimsa is.
Back to the current case, next the anthropocentrist first-aiders turn up:
The stingray that pierced her back was about 4 feet across, and still alive and attached to her until first responders arrived and cut it off.

If I was a first-aider, I would have cut into Cataffo-O'Brien instead of stingray.
The last part reminds us that non-lethal Ahimsa is almost useless:
Still, she’s not scared of returning to the beach once her wounds heal: “I’ve lived in Florida for 35 years now, and I’ll continue to go back into the water,” she adds.
She still thinks it's OK to be "white" in water! She will not stop until she is dead!
