Thank you to Dr. Adrian Smith! Most of the footage in this video is from Dr. Smith's YouTube channel. He has all sorts of wonderful content there, and does a much more thorough job in explaining all of the science behind his work.
Thank you to Dr. Alex Wild! Please look at Dr. Wild's incredible collection of photos: www.alexanderwild.com/
Thank you Dr. Fred Larabee, Josh C. Gibson and DR. Eduardo Fox for their amazing footage.

“Oh, you were bleeping what they were thinking.” That.... was very clever, Jerry.
-
Haha love these ants! Their bite hurts SO MUCH! 🖤🐜🐜🐜🐜🐜
-
"she looks like shes overdoing it a bit but who knows, termite might be talking sh*t" i already love this channel
-
I love how Jerry started as an offhand joke in one of his videos, and now he's a recurring character
-
"Imagine a Wheel of Fortune where the word 'scumbag', is being displayed, but people still have to guess the 's'". Congratulations Zefrank, you outdone yourself
-
"Scary stuff. Like being in kindergarten, and having a biter in the ball-pit" That's so scary and funny at the same time. And, never was an antlion likened so aptly.

God: “Adam, you get one wish.” Adam: “Ants stay small.” God: “Done.”

The way Mildred spun as she flew out of the ant lion pit was definitely the funniest part for me.
-
Not gonna lie. When Mildred turned herself around in the death pit and bit her predator in the face to escape it was pretty badass.
-
“Sticky doorknob” sounds like one of those slang terms you’d look up on Urban Dictionary and immediately regret it.
-
Telling Jerry to show us what he designed after talking about a "recalled sex toy" sounded like we were going to get a very different demonstration.
-
My late Grandma grew up in Guatemala, and told us that the "Indios," as they were commonly known, the native people, would use ants similar to these when suffering a cut that we would see as needing stitches. An ant was held over the cut until its jaws were triggered, closing the wound. The body was quickly twisted off and the head would remain attached as a sort of formic suture. A line of these would stitch up the gash and they were good to go!
-
"Play this in a sex-ed class without telling anyone what it is." For the record, That line caused me to subscribe.

“The bleep button is a privilege, amateur.”

If you've ever wondered what a love child of Sir David Attenborough and Robin Williams would sound like, well now you know

8:38 A bit of a correction: there he's likely referring to the Asian Pericapritermes nitobei termites (who became relatively notorious a while ago for dethroning Mystrium in blow speed), however they don't do the "basically the same thing" at all but employ a very different technique than the one used by Mystrium: the asymmetrical snapping, totally unique to termites. This advanced technique involve highly assimmetrical and very weirdly shaped mandibles (along with a big head full of muscles) and work on a different principle tha the symmetrical snap used by Mystrium (and several termite species aswell), allowing their blows to reach velocities unmatchable by symmetrical snappers (or any other snapping ants). P. nitobei soldiers snaps at up to 121 meters per seconds, well above the 90 meters per second reached by Mystrium, but they're still not the fastest known animal movement in the world: that trophy is currently held by another much larger asymmetrical snapping termite: Neocapritermes taracua from South America. This very interesting species (beside being known for the kamikaze toxic "backpacks" their older workers are equipped with) have soldiers than can snap at a whopping 153 meters per second (as very recently registered by termitologist Jan Sobotnik and his team), which neatly beat P. nitobei's (and shatters Mystrium's) "scores". Said so, though there are a lot of termite species that employ the asymmetrical snapping technique, only these these two had their snap speed measured, so the real "fastest blow in the animal Kingdom" is likely still hiding among them, unknown to us due to a lack of research on termites.

"Butt ants... Sorry, but ants..." This is a joke he uses in so many videos, and yet it ALWAYS gets me.
-
Imagine playing a claw machine with your mustache. Now imagine your mustache moving so incredibly fast that is launches you backwards across the room. That's how the trap jaw ant do.

"but who knows, the termite might be talking sh...BEEP" i lost it... freakn lost it xD

"Biter in the ball pit" hit way to close for me, I was in fact bitten at a McDonald's playhouse ball pit by some dirty ass kid who didn't know what personal space meant. He bit me on the calf while I was trying to do some butterfly stroke type motion lol. Shit hurt and when he finally got taken out he didn't even have a parent with him. Turns out he lived just down the block.
