Who knew our Burmese python Bertha had such vocal range? 😄🎶 Okay… maybe she was just yawning. But it’s not because she’s sleepy... Snakes often yawn to stretch or realign their jaws, especially before or after eating. It helps them stay flexible enough to swallow prey whole! Bertha is one of the largest snakes in the world — and clearly one of the most dramatic too. 🐍 #nrz #thenationalreptilezoo #snakes #BurmesePython #snakeyawn #reptilezoo #trendingtuesday #funnyanimal | The National Reptile
