(Phys.org)—In a single cave in Ecuador, a species of cavefish has evolved to do something perhaps unique to them, navigate with their teeth.
The blind Mexican cavefish (Astyanax mexicanus) have not only lost their sight but have adapted to perpetual darkness by also losing their pigment (albinism) and having altered sleep patterns. New research published in BioMed ...
Adapting to darkness: How behavioral and genetic changes helped cavefish survive extreme environment
University of Maryland biologists have identified how changes in both behavior and genetics led to the evolution of the Mexican blind cavefish (Astyanax mexicanus) from its sighted, surface-dwelling ancestor.
(PhysOrg.com) -- A blind fish that has evolved a unique technique for sensing motion may inspire a new generation of sensors that perform better than current active sonar.
