Ozark Hellbender

Quick Stats

Lifespan: 25-30 years

Size: Length: 30-60 cm (12-24 inches)

Diet: Carnivore

Habitat: Clean, fast-flowing streams with rocky substrates

Life Cycle Information

Reproduction: Mating usually occurs in the fall. Males prepare and guard underwater nests, enticing females to lay eggs within.

Growth: Direct development; larvae resemble miniature adults.

Habitat & Distribution

Original Native Range: Ozark region of southern Missouri and northern Arkansas.

Current Native Range: Restricted to parts of the original range, with significant population declines noted.

Diet

Primary Food Source: Crayfish, which make up a significant portion of their diet, as well as small fish and aquatic insects.

Feeding Behavior: Nocturnal predator.

Predators & Threats

Natural Predators: Larger fish and other carnivorous animals.

Human Impact: The greatest threats include habitat destruction, especially due to siltation from mining and agricultural runoff, collection for the pet trade, and disease (such as chytrid fungus).

Role in Ecosystem

Ecological Importance: They play a vital role in controlling crayfish populations and are indicators of healthy freshwater ecosystems.

Tips for Supporting Ozark Hellbender Conservation

Advocate for responsible mining and agricultural practices that reduce siltation in waterways.

Educate others about the importance of clean, unpolluted waterways and the species that rely on them.

Support or volunteer for conservation projects aimed at monitoring and restoring Ozark Hellbender populations.

12. Fun Fact

Unlike many other amphibians, the Ozark Hellbender does not have an aquatic larval stage with gills; instead, young Ozark Hellbenders look like smaller versions of the adults and breathe through their skin from the start.

The Ozark Hellbender is especially at risk and warrants significant conservation attention. Making this information accessible and clear can be an important step toward raising awareness and galvanizing support for conservation efforts.
