News this morning tells of the successful in-captivity breeding by an English aquarium of South American frogs which have a poison 200 times more powerful than morphine. The species, Phantasmal poison frogs, is bright red with three greenish fluorescent stripes, and is classed as endangered - with populations only surviving in seven (known) sites in Ecuador. Now the most interesting thing about these incredibly poisonous frogs - which was mentioned in the last paragraph of the news item I saw - is that their toxins can block pain 200 times more effectively than morphine without addiction and more serious side effects. (On re-reading the article, it was mentioned earlier - but I missed it in my haste to read the article to see why they were putting the effort in to saving this extremely rare poisonous amphibian.)
