Pickerel

"The skin secretions of a stressed Pickerel Frog are known to be toxic to other frogs, as many a novice frog catcher has found when he finds only the Pickerel Frog still alive in his bucket. These secretions can also be moderately irritating if they come in contact with the eyes, mucous membranes, or broken skin. It is advisable to wash one's hands after handling Pickerel Frogs."
