Columbian poison dart frogs
It is considered to be one of the most toxic animals on Earth, Columbian poison dart frogs have enough venom to kill ten grown humans.
Columbian poison dart frogs are tiny, beautiful, and deadly.
They produce a poison called histrionicotoxin, which is an amine that causes paralysis.
Death from histrionicotoxin results by suffocation through paralysis of the victim's respiratory muscles.
Curare, the Amazonian arrow poison that is a mixture of compounds, from a woody wine, contains another paralytic neurotoxin,
called d‐tubocurarine. Histrionicotoxin and d‐tubocurarine both block the action of acetylcholine,
an important neurotransmitter.
Adrenaline, the hormone responsible for our “fight‐or‐flight” responses in certain situations.
The amines can be regarded as compounds based on , NH3, with one, two or three
of the hydrogen atoms substituted by an alkyl or aryl group, R.
