The Blanco blind salamander (Eurycea robusta) is a special kind of salamander that lives in water. It doesn't have lungs like us; instead, it breathes through its skin and gills! This salamander is found only in a very small area of the Blanco River in Texas, near a city called San Marcos. It lives deep underground in limestone caves and cracks, which are called karst formations. Because it lives so deep, it's very hard for scientists to find and study them. So far, we only know about one single Blanco blind salamander that was found way back in the 1950s.

What is the Blanco Blind Salamander?
The Blanco blind salamander is a unique creature. It's called "blind" because it lives in total darkness underground and doesn't need to see. It's also known as a "lost species." This means scientists aren't sure if it's still alive today or if it has disappeared forever.
A Rare Discovery
In 1951, something exciting happened. A company was digging for gravel in the dry bed of the Blanco River. They found four of these rare salamanders!
- Sadly, two of them were eaten by a heron (a type of bird).
- One salamander got lost.
- The last one was sent to the University of Texas at Austin so scientists could study it. This is the only specimen we know about.
Where Do They Live?
Scientists believe that if any Blanco blind salamanders are still alive, they live deep inside the Edwards Aquifer. An aquifer is like a giant underground sponge made of rock that holds water. It's a huge system of underground rivers and caves.
Searching for Clues
Researchers are trying hard to find out if the Blanco blind salamander still exists. They use a special method called "environmental DNA analysis." This means they look for tiny bits of DNA that animals leave behind in the water, like skin cells or waste.
However, it's tough because they don't have any fresh DNA samples from a Blanco blind salamander. So, they are studying DNA from similar salamanders, like the Texas blind salamander. This helps them learn more about what the Blanco blind salamander's DNA might look like. Hopefully, one day, they will find proof that this amazing creature is still out there!
