YouTuber Retic over at Prehistoric Pets TV has a huge collection of pythons and other ancient creatures. Here he shows how and why a clutch of python eggs can be lifted up in giant sticky clumps.

When you think of eggs, you probably picture a chicken egg, with an eggshell that is hard and easy to crack. However, like many reptiles, python eggs have shells that are soft and paper-like. When a python mom lays eggs, they are a little wet. Before they dry, she will gather all of her eggs into a ball shape.
