Unlike the embryos of other vertebrates, early snake embryos coil as they get longer, typically forming clockwise spirals. A new study offers an explanation for why embryonic snakes go through these contortions—and why they tend to curve in one direction. Learn more: scim.ag/4ygkAQk
Snake embryos often coil in one direction. Now, we may know why

“A slow, heavy desert lizard called the Gila monster can go months between meals. In the early 1990s, a physician-scientist named John Eng grew curious about how it keeps its blood sugar steady across those long fasts… Years later, a synthetic version of that molecule became the first GLP-1 drugs”

Soras are quite shy and spend the majority of their time lurking in reed beds. But what happens when you are hunting amongst the reeds, catch a bug, and need to take it back to your chicks … across an open gap? YOU SPRINT FOR IT! Those feet were made for that! #Birds #photography #wildlife 🪶
A Sora rail sprints out from the safety of reeds in a shallow marshes. It has mottled brown and white feathers with a black face mask and a candy corn yellow beak. In its beak is a fairly large insect that it is taking back to feed its chicks.
