The blind catfish—known as a Mexican blindcat—was recorded by a team from the University of Texas at Austin after being spotted and captured swimming near Del Rio in Texas.

The tiny, 3in-long fish, identified as the Mexican blindcat, were collected by a team in May and reported this week by the University of Texas Austin.

Hendrickson has spent years searching for the Mexican blindcat in the US.

Texas has two other species of blind catfish: the toothless blindcat and the widemouth blindcat, which live deep in the aquifer below San Antonio.

The Mexican blindcat was first documented in 1954, after scientists discovered the miniature fish swimming in the dark wells and springs of northern Mexico.
