How are snakes and worms different?
While most snakes have scaly exteriors, worm epidermises vary depending on the species. The common earthworm, for example, has a pink, segmented body, and it can breathe through its skin. While terrestrial snakes have dry bodies, most terrestrial worms excrete a layer of mucus to help them breathe and stay moist.
Are worms and snakes in the same family?

Do snakes grow new vertebrae?
The researchers thought that a change in the way Oct4 was turned on and off was responsible for the evolution of the snake’s long body, causing embryos to make more trunk vertebrae. To test this theory, they manipulated the Oct4 gene in mice embryos and found that the animals did indeed grow more trunk vertebrae.
Which body part does a snake use to detect smell?
Snakes have also developed a highly a specialized scent organ known as the Jacobson organ, which allows them to literally taste and smell the air! The Jacobson organ is found at the base the snake’s nasal cavity. The organ has two ducts that reach down to the roof of the snake’s mouth.

Why do snakes get so big?
Human influence appears to have caused some snakes in the wild to grow to very large sizes.

The swallowing takes most of the time. “It would be extremely difficult for me to save my life without help,” Greene said.
