Related to the above, I read that a mountain in NH just set the record for the coldest windchill. -106 F. -45 F temperature with 97 mph wind.

There is no antidote for a blue-ringed octopus bite. However, if you can get a ventilator to breathe for you for 15 hours, you survive with no side effects

Tetrodotoxin

It's not as simple as that. Unlike classic paralytics (curare), TDX is a sodium-channel blocker whose effects are far wider-reaching than simply blocking the interaction of nerve and muscle.

This actually "paralyzes" the nerve itself.

It is the same shit as in pufferfish.

@George-K so, you will not be fine if you are vented for 15 hours?

Perhaps, perhaps not. It's not as simple as a paralytic (curare-type) drug.

Curare and drugs that I used act by physically blocking the receptor on the muscle side of the synapse between muscle and nerve. So, if the nerve fires, the muscle doesn't see the neurotransmitter.

TTX works on the sodium channel, which causes the nerve to fire.

Note that many of these symptoms are not related to muscular paralysis.

This is a 773 gram polished Chinga meteorite. The quarter-cut specimen was found in Turvinskaya, Russia and has been cut and polished on two sides. The rest of the meteorite retains its natural light brown crust, creating a dramatic contrast.
