What to know about Snakes aren’t simple tubes. Their bodies have five regions – including a short neck

The author presents new research published in the Journal of Morphology regarding the vertebral structure of snakes. The study identifies five distinct body regions instead of the previously accepted four and suggests that snake necks are shorter than earlier research indicated.

What happened

Snakes are seemingly simple in structure, a head attached to a long unremarkable noodle.

Why it matters

They do have some pretty cool features at the front end, with venomous fangs and the capability to stretch their mouths and swallow large prey whole, but their bodies are not just the simple tubes we once thought.

Common ground

My new research, published today in the Journal of Morphology, reveals their body structure to be surprisingly complex – far more than we once thought.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.

Claim 2: “We also found a previously undescribed region, which we are calling the middle thoracic region, as it’s nestled in between the anterior and posterior and thoracic regions.”
