    There's a particular wetland near my home in West Virginia in which I've found what I feel is an inordinate amount of frogs and salamanders with additional or malformed legs, I always assumed it was due to pollution due to quite a few industrial facilities (powerhouses, steel mills, chemical plants, and natural gas compressor and metering stations) and the coal mining runoff in years past. I'm sure that has some effect, but I'd be very interested to learn whether there's a lot of that family of worms in the water. Interestingly, it's a natural wetland, but only sorta. It's along the Ohio river, and if left to nature would probably be under the river's surface almost all year, but since we built many locks and dams along the river to make it year-round navigable the river channel has become narrower and deeper, exposing the wetland to year-round air.

    Side note, how the hell does a creepy parasite video from smart folks like the SciShow crew not mention the mind-control cordyceps fungi?! Good vid just the same, I'd never heard of the frog mutating worms or the crab manipulating barnacles.

    The name of the Raflesia was actually the name the 2 people who found the flower, I forgot the last part of the name, but it was pretty old for me, so it would make sense
