What unique physical feature allows the Rhombic Egg-Eater to swallow eggs larger than its own head diameter?

Answer

Unique vertebral adaptations

The Rhombic Egg-Eater, a notable species in this group, possesses unique vertebral adaptations that are crucial for its specialized feeding habit. These skeletal modifications enable the snake to effectively crush and swallow eggs that are significantly larger in diameter than its own head. Following the consumption and crushing process, the snake subsequently regurgitates the resulting eggshells, which aids in nutrient absorption without the burden of the indigestible shell material. This adaptation is central to their existence as dedicated egg consumers.
