This tiny blue flower can kill a humpback whale

Illustration for article titled This tiny blue flower can kill a humpback whale

The humpback whale is one of Earth's largest creatures, with an average weight of around 40 tons. But as it turns out, this gigantic creature is vulnerable to the toxins of a much smaller living thing: Aconitum delphinifolium, better known as Larkspur monkshood.


Aconitum was on our list of 10 killer plants, and with good reason: it contains both neurotoxins and cardiotoxins. In China, some warriors recognized monkshood's properties as a biological weapon, coating the tips of their arrows in the poison. But in Alaska, the Alutiiq discovered that Aconitum could take down something far larger than a human. Whaling was dangerous business, and Aconitum was a key part of an important hunting ritual. The whalers would mix the toxic flower with human fat — for its spiritual significance — and then apply the mixture to their spears. Even if the spears themselves didn't kill the whales, the toxin would finish the job in just a few days. The dead whales would wash up on shore, and the villagers would be lousy with blubber.

Heather Pringle's article on Alutiiq whaling is worth a read, even beyond the tidbit about the deadly buttercup. These whalers were treated as magical men, and would have to sequester themselves from the rest of the village before a hunt. I do wonder how they figured out the flower's whale-killing properties, and how many other poisonous plants they tested on the mighty humpback.

Where the hell did they get human fat??????? (Well, besides the obvious answer.)
