Hellbenders are fully aquatic, which means they cannot live out of water and do not try to crawl out of their stream or river habitat. As river water flows over their body, oxygen is taken up by tiny blood vessels in the skin and carbon dioxide is released
ATP stores and transports energy in the cells, usually in the mitochondria. Energy is released by hydrolysis (carbohydrates being broken down into sugar molecules), which eventually results in forming ADP (adenosine diphosphate) that absorbs the energy and recharges the phosphate group and ATP
Birds and bats are the most common predators
