Would you believe a tiny flower was used to take down the largest prey on earth? Great story here:
Each July, along the dappled stream banks of Kodiak Island, just off the Alaska coast, a weedy looking wildflower produces a few dark-blue hooded blossoms. There is nothing particularly memorable about the appearance of Aconitum delphinifolum. Its leaves are thin and rather spiky. Its scrawny-looking stem cannot hold the weight of its flowers: its neighbors keep it upright. But this eminently forgettable looking plant, a member of the buttercup family, possesses a dark secret. Aconitum delphinifolum contains a toxin capable of killing one of the world’s largest animals, a 40-ton humpback whale.
