Description
The mexican tetra (Astyanax mexicanus) presents fascinating opportunities for the study of evolutionary traits. This subtropical American species has two variants, one a surface-dweller and one that thrives in underwater caves. The latter variant has several unique traits, including a complete lack of eyes. Comparing the two helps scientists learn much about cave adaptation and the process of evolution. It is a popular ornamental fish for aquariums.
