Don't get any ideas, though, frog-lickers!
These guys are still POISONOUS!
Queen University's Herpetologist Valerie Clark recently discovered that the skin of Madagascar poison frogs actually contain the sugar sucrose, which marks them as the first known case of the chemical being produced by an animal, and not a plant!
It seems like it may be caused by their diet, as the frogs eat ants, who in turn, acquire the sugar from the sap of the plants in which they live!
However, as we mentioned - that's not all they secrete!
As Clark's colleagues documented, there's also tauromantellic acid coming out of these amphibians, which is the "first example of a genuine poison frog metabolite from the skin of any tropical poison frog. It is interesting to speculate on the reason for the presence of this unusual bile acid in poison frog skin, and it is possible that this compound plays a key role in sequestering alkaloids and protecting the frogs from their own toxicity."
Crazy! Talk about sweet AND sour!
