Holiday Pop Quiz: Metal Band or Microbe?S

It's time to test your scientific acumen — or your knowledge of a very specific musical subculture. Plenty of microbes have seriously badass names. Lots of metal bands have names that sound like weird microbial diseases. Can you tell the difference between Thergothon and Eperythrozoon? Take our quiz!

Here's how this works: below you'll find a list of 20 names. They are all either names of metal bands or names of microbial taxa (or, in some cases, both). Take a look at the list and keep score.
