Snakes: Mouths
built 231 days ago
While the majority of snakes eat a variety of prey animals, there is some specialization by some species. King cobras and the Australian Bandy-bandy consume other snakes. Pareas iwesakii and other snail-eating Colubrids of subfamily Pareatinae have more teeth on the right side of their mouths than on the left, as the shells of their prey usually spiral clockwise[17][18]

Some snakes do have traces of hind limbs, or spurs.However, there is no snake that uses these for walking. Snakes have no external ears, they hear by sensing vibration through a delicate bone structure. Snakes "smell" with a sensory organ on the roof of their mouths. Their tongue is used to pick up scents from the air, and bring them into their mouth.

Venomous snakes that use hemotoxins usually have the fangs that secrete the venom in the front of their mouths, making it easier for them to inject the venom into their victims. Some snakes that use neurotoxins, such as the mildly venomous mangrove snake, may have their fangs located in the back of their mouths, with the fangs curled backwards. This makes it both difficult for the snake to use its venom and for scientists to milk them.
