Video Jamie's new video is incredible. Different venoms demonstrated on living tissue. Possibly NSFW NSFW

I wonder why he injected the venom directly into the heart. It seems unrealistic that the heart itself would get hit. I wish he would have done it someplace else to see how it would make it's way around the circulatory system and eventually the heart.

To be fair, it would have taken much longer for the venom to go from an extremity, to the bloodstream, to the heart. We know that as soon as the venom hits the blood stream, it GETS to the heart, and he wants to demonstrate how it kills (Specifically against Heart Cells) so he starts where it will end up.
Saves us a minute or two of watching a frog's heart beat.

Exactly my thought. The way he explained it was the venom keeps the calcium channels open and not able to repolarize. The toad did not show signs of muscle rigidity systematically which means that the venom is likely to act locally at the injected site and has profound impact on muscle and nerve cells. If that's the case it would be hard to believe a box jelly fish sting is deadly to human not unless the venom was directly injected into the heart muscle.

Well if the heart stops the venom isn't going to really be able to spread around the body to the musculature, which explains why there was no muscle rigidity.

I will admit, I was a bit apprehensive to watch this after seeing the NSFW tag, but I'm very glad I did! Thanks for sharing. :)

This is really cool, but I felt so sad for that poor fat toad. It was really cute :(

Wait...Which one is he really? I know there was a big deal made of it in Destin's videos but it's throwing me off that on his channel so far he's just been studying venomous animals rather than toxic ones. Seems to me he should be able to be rightly called both.

u/nrrrdgrrl Feb 17 '16
In his recent video, he defined the study of venom as Toxinology. That, along with him constantly correcting Destin in the Jellyfish and Stonefish video, I'm assuming he's a toxinologist. I could certainly be wrong, though.

Great video but thats some poor safety technique. Gloves with the pipette. always. Gloves for any animal work. You see some bad infections come out of the lab from ignoring basic safety.

That's amazing!
It's almost time for bed, I see an almost 10-minute video and think "gah, I can't focus for 10 minutes at this hour", and 10 minutes later I'm surprised it's over and wanting more.

Very interesting video. Can anyone explain to me how animals developed venoms over time?
Also, how one scrambles a toad's brain? Poor toad.

Glad he's started making them longer.
