Ep. 55 - Bill and Steve Go to Hell(benders)

What’s dark and slimy and over two feet long? It’s an Eastern Hellbender! This aquatic giant salamander, endemic to the eastern and central US, is the largest amphibian in North America, often weighing in at over 4 lbs.! The hellbender (Cryptobranchus alleganiensis) is, not unlike Steve, secretive and slimy but also fascinating. Join the guys for one hell of an episode learning about this rare and disappearing denizen of fast-moving streams.

This episode was recorded on January 22, 2022 at Chestnut Ridge County Park in Orchard Park, NY.

Episode Notes

Bill said that the Kinzua Bridge was about 300 feet long, but he was mistaken. The bridge was about 300 feet high. The length was 2,053 feet.

When Bill was talking about the white tips on hellbender toes, he mistakenly said that hellbenders have “fingers”. D’oh! Bill understand that salamanders don’t have toes, but he wants everyone to know he was using the term in a cutesy way.

Steve mentioned his friend Zachary Cava and Zack’s research into hellbenders. Bill was able to track down Zack’s study! Full citation below under “Works Cited”.

Around the 20:50 mark, Steve wonders if there is an ecological concept or law stating that larger species tend to go extinct more quickly than small species. After recording, Bill did some searching but could not find any specific law. Anyone out there that knows of one? Please get in touch with us!

Bill gave a quick and somewhat vague definition of siltation. Here’s a more complete definition: Siltation refers both to the increased concentration of suspended sediments and to the increased accumulation of fine sediments on [waterway] bottoms where they are undesirable.
