Is This The Toughest Fish in The World?
There's a fish that lives in the pools of a cave called Cueva del Azufre in the town of Tabasco, Mexico, that is somehow able to thrive even though its habitat is full of toxins.
Hydrogen sulphide, a toxic chemical, seeps into the water from oil deposits and nearby volcanic activity. The compound also permeates the air, making it toxic for humans to breathe, reports The BBC.
These mysterious "cave molly" fish live in water that is 50 times more toxic than what's considered fatal for aquatic life. How can they survive?
