box jellyfish, blue ringed octopus and sea snakes all have more potent venoms. i'm pretty sure the poison in the pufferfish is more poisonous too.

Well, I played black and white ping pong. So there.

lots of awesome frog pics and spooky ass froglore data in here ( as well as a lot of frothy cucks). 10/10 thread.

The strange thing about these frogs is they are only poisonous if they have been feeding in their own native habitat, otherwise they lose their poison. Scientists are still not certain exactly why that is.

best I can tell the sheer lethality of these frogs ha freaked (gay)enter right the hell out. And hes taking his anger out on other people in this thread because of how fucking deadly and persistent this frogs toxic excretions are.
by his reaction you would think he lives in a rainforest and not his marms basement

Batrachotoxin (BTX) is an extremely potent cardiotoxic and neurotoxic steroidal alkaloid found in certain species of frogs (poison dart frog), melyrid beetles, and birds (the pitohui, blue-capped ifrit, and little shrikethrush). Batrachotoxin was derived from the Greek word βάτραχος bátrachos "frog".[2] Structurally-related chemical compounds are often referred to collectively as batrachotoxins.
The "poison dart" (or "poison arrow") frog does not produce batrachotoxin itself. It is believed that the frogs get the poison from eating beetles or other insects in their native habitat. Frogs raised in captivity do not produce batrachotoxin, and thus may be handled without risk. However, this limits the amount of batrachotoxin available for research as 10,000 frogs yielded only 180 mg of batrachotoxin.[9] As these frogs are endangered, their harvest is unethical. Biosynthetic studies are also challenged by the slow rate of synthesis of batrachotoxin.[3]
The native habitat of poison dart frogs is the warm regions of Central America and South America, in which the humidity is around 80 percent.
Of the three so-called "poison dart" frogs which contain batrachotoxin—golden poison frog, Kokoe poison frog, and neari—the most toxic is the most recently discovered golden poison frog, which generally contains 27 times more batrachotoxin than its close relatives and is 20-fold more toxic.
Batrachotoxin (BTX) irreversibly binds to the Na+ channels which causes a conformational change in the channels that forces the sodium channels to remain open. Batrachotoxin not only keeps voltage-gated sodium channels open, but it also reduces the single-channel conductance. In other words, the toxin binds to the sodium channel and keeps the membrane permeable to sodium ions in an all or none manner.[8] This has a direct effect on the peripheral nervous system (PNS). Batrachotoxin in the PNS produces increased permeability (selective and irreversible) of the resting cell membrane to sodium ions, without changing potassium or calcium concentration. This influx of sodium depolarizes the formerly polarized cell membrane. Batrachotoxin also alters the ion selectivity of the ion channel by increasing the permeability of the channel toward larger cations. Voltage-sensitive sodium channels become persistently active at the resting membrane potential. Batrachotoxin kills by permanently blocking nerve signal transmission to the muscles. Batrachotoxin binds to and irreversibly opens the sodium channels of nerve cells and prevent them from closing. The neuron can no longer send signals and this results in paralysis.
Currently, no effective antidote exists for the treatment of batrachotoxin poisoning.
