The Yucatán mushroomtongue salamander (Bolitoglossa yucatana), also known as the Yucatán salamander, is a species of salamander in the family Plethodontidae. It is found in the Yucatan Peninsula of Mexico and extreme northern Belize, possibly reaching into Guatemala.[2]
Its natural habitats are lowland tropical forest and thorn forest below 150 m (490 ft) above sea level. It also occurs in disturbed habitat around villages. It is mainly terrestrial, living on the forest floor under surface debris, and in sink holes. However, it can also live in arboreal bromeliads. It is threatened by habitat loss. It occurs in the Calakmul Biosphere Reserve in Mexico and in the Shipstern Conservation & Management Area and Fireburn Nature Reserve in Belize.[1]

Rare Blind Cavefish in Mexican cave system!
Transcription
Life is tough in the darkness. This is a catfish that couldn't find its way out. Christine searches for another mass of tree roots that might harbor a cavefish. When we find one, I start looking carefully in the roots. At last I spot it! A pinkish white fish hiding in there! It's great to see, but impossible to film in that tangled mess. Fortunately for me, the fish shies away from light and swims out of the roots. Even though this species of fish has evolved for thousands of years in the complete absence of light and has no eyes, it can still detect the presence of light through its albino skin using a gland in its head. Why? This fish's only defense is darkness. If it wanders out of the dark part of the cave, other fish can see it—but it won't see them. The blind cavefish needs to stay in the dark where it's safe. My lights make the cavefish swim for cover and safety. The fish that followed me into the cave from outside take an interest in the cavefish. I have to shoo them away. In fact, in the cave ecosystem, this little fish is the top predator—the Great White shark if you will, of the cave! With our mission complete, it's time for me and Christine to turn around and head back out to the light.
