Meet the biggest (and weirdest looking) salamander in the U.S. — the hellbender. Like many amphibians, these giants are dying off at alarming rates. We followed a team who are trying to reintroduce hellbender babies to the wild before it's too late. | OPB

8.3K views · 162 reactions | It's amphibian week, how could we not highlight the amazing Hellbender!?✨ Rather than using their lungs to breathe, hellbenders absorb oxygen through their wrinkled skin. The wrinkles give the hellbender more surface area to absorb greater amounts of oxygen. #tennesseeaquarium #aquatic #salamander #hellbender #amphibians #chattanooga #trendy #education | Tennessee Aquarium | Facebook
