Bottomfeeder;2556716; said:Tetradoxin? as in Puffers? Wow! How many MU? (Mouse Units, a recent discovery of mine...according to Endless 0cean, a Tiger Puffer contains over 1000 Mouse Units, 1 MU being able to kill a 1-0z Mouse in 30 mins.)
Mean total skin TTX levels of newts ranged from no detectable TTX to 4.69 mg/newt and differed among populations

The lethal potency is 5000 to 6000 MU/mg

Do the math and that gives the Willamette Valley newts (highest amounts of ttx) a value of over 25,000 MU!
To think how much I played with these as a child... and still do.



some people like them some people well thank they all are trying to kill us.
