While chowing down on scorpion tail, I also tried water bugs, various worms, and a couple tarantula legs. The tarantula that you eat is usually farmed by the family that is selling them, and they are bred in a way that they are not poisonous. While I quickly learned I do not like things that squish, the idea of eating the body made my stomach flip, so I stuck with the legs. It was crunchy, and as it was deep fried, there was no hair. You really would not be able to tell what it was. While tarantulas are now a tourist attraction or a must try for extreme eaters, the idea is believed to have originated during the genocide of the Khmer Rouge era, where it was "eat tarantula or starve."
Speaking of worms, I did try the Bamboo Worm, which is a favorite throughout South East Asia as it is similar to "buttery popcorn," I was told. Perhaps the person wanted me to try them or they were prepared incorrectly, but squishing a worm that squirts is not a form of popcorn I've ever had!
