Meaning and Definition
A milky secretion, containing toxic substances, produced by the skin glands of true toads (genus Bufo) and some other related amphibians.
A complex mixture of steroids, alkaloids, peptides, and other biologically active compounds serving as a defense mechanism against predators. In some contexts, it can refer to toxins derived from any amphibian skin secretion, though this is technically imprecise.

FAQ
Frequently Asked Questions
No. While both are amphibian skin toxins, bufotoxin is specific to toads of the family Bufonidae (especially genus Bufo). Poison dart frog toxins are chemically distinct and are called batrachotoxins or pumiliotoxins.
It is highly unlikely to be fatal to a healthy adult from casual contact, but it can cause severe irritation to mucous membranes (eyes, mouth). If ingested in sufficient quantity (e.g., by a pet dog), it can be lethal due to its effects on the heart.
Components of bufotoxin, particularly bufadienolides, have been studied for their potential effects on heart function and, more recently, in cancer research, though they are highly toxic and not used directly in medicine.
Wash your hands thoroughly with soap and water after handling any toad, and avoid touching your eyes or mouth beforehand. It is not absorbed through intact skin in dangerous amounts, but the secretion can be an irritant.
A milky secretion, containing toxic substances, produced by the skin glands of true toads (genus Bufo) and some other related amphibians.
