The Mexican tetra (Astyanax mexicanus) is a small, freshwater fish native to Mexico, Texas, and New Mexico. Depending on environment, the species has two distinct forms: a surface dwelling form and a cave-dwelling form (also known as the blind cavefish). In the latter, as the fish matures, skin grows over the eyes and ultimately impairs vision. More...These fish may provide insight into retinal degeneration in humans. Less...
