What specific action does the Rhombic Egg-Eater perform to expel dry shell fragments?
Answer
Violent side-to-side heaving motions/reverse flexing
Once the contents of the egg—the yolk and albumen—have been squeezed out and absorbed into the digestive tract via the internal bony grinding process, the snake must rid itself of the hard remnants. This expulsion is accomplished through a specialized maneuver involving reversing the body's mechanics. The snake flexes its body in reverse, often accompanying this with violent side-to-side heaving motions. This action is necessary and characteristic, allowing the snake to regurgitate the resulting dry, empty shell fragments, providing a visible confirmation that the meal has been successfully processed.
