Hooser Cavefish with its flesh cleared to show the lack of eyes

Researchers have described a new species in the caves of Southern Indiana, which has been named Amblyopsis Hoosieri or Hoosier Cavefish. Matthew L.

He then teamed up with Prosanta Chakrabarty and Jacques A. Prejean from Louisiana State University. They collected 30 fish from Indiana and 11 from Kentucky, which revealed that the Indiana fish included a new species.  hooser
