In Africa, there is a species of snake scientifically known as Dasypeltis scabra. These snakes are remarkably agile, moving swiftly across rocky surfaces and through foliage.
This species features a small, narrow head and a slender body, typically measuring about 0.8 meters in length. Their eyes possess vertically elongated pupils. The scales along their sides are tiny but have distinct edges. Their tails are relatively short, while their dorsal coloration ranges from gray, brown-gray, to brownish-green. They exhibit dark spots along their backs and black markings on their sides. Notably, there are two V-shaped markings on the top of their heads, with a similar V marking located just behind their necks.
Despite their somewhat intimidating appearance, these snakes pose no threat to humans.

This species is aptly named “egg-eating snake” due to its unique diet. They exclusively consume the eggs of various bird species. You might be surprised to witness them devouring eggs that are three times the diameter of their heads. Despite their small size, they can even consume chicken eggs. The Dasypeltis scabra hunts for eggs both on the ground and in trees, primarily at night. However, they are occasionally observed foraging during the day.
The egg-eating snake possesses an extraordinarily flexible jaw structure, allowing it to significantly widen its mouth. When swallowing an egg (which can be nearly double the size of its head), the snake pushes the egg backward into its mouth and gradually swallows it using the elasticity of ligaments connecting its lower jaw halves. As this snake has only a few small teeth on each jaw, it does not encounter any hindrance while swallowing the egg. During the swallowing process, small scales on their necks stand erect, exposing the underlying skin.
Most other snake species typically consume eggs with soft shells (such as lizard eggs or snake eggs) because they lack the specialized “tools” to break through hard egg shells. However, the egg-eating snake Dasypeltis scabra possesses specialized serrated structures located deep within its throat. These structures, formed by cervical vertebrae, function to puncture the eggshell. When the egg reaches the throat, these specialized structures break through the shell, allowing the contents to be swallowed while the shell is expelled.
During the summer, female Dasypeltis scabra lay between 6 to 25 eggs. Interestingly, these females tend to deposit their eggs in various locations rather than laying all their eggs in a single nest.
In seasons of abundant bird nesting, these snakes strive to consume as many eggs as possible to build up fat reserves. They rely on this stored fat during the other seasons of the year when they find it challenging to locate and consume eggs.
