Unique Features of Snakes

Snakes' flexible jaws allow them to swallow prey much larger than their head. Some large snakes can even eat cows and crocodiles.

A few species also carry potent venom. For example, the King Cobra is the world's largest venomous snake, reaching 18 feet long. 

These creatures have transparent scales, called "brilles," instead of eyelids, which shed along with their skin during molting. 

A snake's forked tongue is part of a sensory organ known as Jacobson's organ, which enables them to track their prey using chemical cues. 

They can sense vibrations through their jaws, which travel to their inner ear, allowing them to detect prey and potential threats.
