Paul Rosolie tells Joe Rogan the Amazon at night is a "Festival of Sex and Death," and a caterpillar scared him more than anacondas. Paul Rosolie: You have to be pretty stupid to get eaten by an anaconda. You know not to go up to your chest in certain swamps. Joe Rogan: Just walking around knowing there are giant snakes, and you're up to your chest in water? Get the hell out of there. Paul: Forget the giant snakes. Fall into that nightmare soup at two in the morning, with black water, insects going up your pants and tarantulas walking on the water eating frogs. It's a Festival of Sex and Death. When we go in to research frogs, we put our socks over our pants. Paul: One girl got bitten about 16 times by a giant aquatic spider-type thing that kept pumping venom into her leg. The emotional toll was worse than the pain. She took some Benadryl and slept it off. She was slapping her leg trying to get it to stop, and it just bit her more. She never even knew what it was. Joe: It could be a new species. Paul: We don't have a real accounting of all the species. Paul: People say a bullet ant is the worst bite. I've been stung by bullet ants about eight times. They suck, but I found a caterpillar on a leaf, it fell on my hand, and I got electroshock waves of pain, way worse than a bullet ant. It messed me up for days. Paul: I got scared and wondered if I had to leave the forest. We used forceps to move the hair aside, and underneath it had barbs like little Christmas trees. Joe: What the hell. Paul: When we get stung by a bullet ant, we say your day is over, and it's funny. This wasn't funny. Eight bullet ant stings never scared him. One caterpillar did.
