This animal is extremely poisonous, producing, among other things, zetekitoxin AB. This is a tetrodotoxin compound that blocks voltage-dependent sodium channels. You’d think, from that name, that if you accidentally touched one of these guy, you could treat it by eating salt and increasing your body voltage. This is not true. Were you to do this, all you would do is confuse the medical examiner as to whether you were poisoned, electrocuted, or choked on a pretzel.
