Talk about a butthead...

Researchers announced this week that they have discovered a brand new species of cave-dwelling fish in Mammoth Cave system's southern Indiana regions. The very appropriately named "Hoosier Cavefish" is the first new species of cavefish to be found in the United States in over 40 years.

What truly makes this fish remarakable however is what it sports on its forehead. The Hoosier cavefish displays an anus in a location where most other animals exhibit literally anything else.

Not pictured: eyes.

We're not sure what the Hoosier cavefish's ancestors did to deserve this fate, but it couldn't have been something good. We will never stop marvelling at Mother Nature's ability to craft things that are unapologetically strange.
