The video shows Khepari eating her own shed skin. I've seen many Amphibians do this. Eating their own shed skin (Dermatophagy) is good for them as it has protein, nutrients, etc. I'm guessing it must taste good as well.
Khepari is a female Kaloula pulchra (commonly known as "Chubby Frog" or "Banded Bullfrog"). She is one of my oldest Amphibians, and is absolutely amazing. She had a male counterpart named Pulch, but he has since passed away.
