I'm pretty sure I'd never heard of "Breaking Trail" before, but it's a program from Brave Wilderness Productions that "leaves the map behind and follows adventurer and animal expert Coyote Peterson and his crew as they encounter a variety of wildlife in the most amazing environments on the planet!", apparently.
It's overly-frenetic/earnest for my tastes (which seems to be the only way non-Attenborough nature shows are allowed to exist nowadays), but this particular clip's amazing, regardless.
On this episode of Breaking Trail, Coyote and the crew discover a frog with transparent skin! Known as the Glass Frog, these amphibians of Central America are known for their translucent belly skin that allows onlookers to see right into their digestive and circulatory systems. Seriously…when observed at the correct angle you can witness the blood pumping in and out of this tiny frogs hearts! Get ready to witness the the Incredible Invisible Frog!
