Raising Hellbenders
In 2011, we successfully bred Ozark hellbendersit was the first time in the world that these animals were bred in a zoo.
Seven years later, those babies were old enough to produce their own babies.
Releasing Hellbenders in Missouri Rivers
Few people are aware that hellbenders are found in Missouri rivers.
With the help of our partners, we release our Zoo youngsters back into the exact river from which they came.
How You Can Help
Keep Missouri rivers clean!
Hellbenders need clean water to survive.
Don't use yard chemicals, and volunteer to clean up streams and rivers.
