The New York Times: This tiny snake has a big mouth
UC biologist discovers surprising distinction for harmless little African snake
The New York Times highlighted a discovery by a University of Cincinnati biologist that a harmless little African snake can eat the biggest prey relative to its size of any known snake.
UC Professor Bruce Jayne has spent years studying the extreme limits of snake abilities in his lab in UC's College of Arts and Sciences. His work has revealed surprising ways that snakes move and the incredible ways they hunt and swallow prey without benefit of hands, paws or claws.
His latest discovery revealed that the champion eater among snakes appears to be a drab little nonvenomous species, Dasypeltis gansi, or the Gans' egg-eater. True to its name, the snake swallows eggs whole before cracking them with its spine and spitting out the broken shell.

While Burmese pythons can consume deer and 100-pound alligators, these meals still don't measure up to those consumed by the little egg-eater relative to either its length or mass.
Jayne presented his findings in the Journal of Zoology.
“This particular group of snakes may be No. 1 when it comes to big mouths in the snake kingdom,” Jayne told the Times.
Associate Professor Bryan Maritz at the University of the Western Cape in South Africa was not part of the study but has been conducting similar research on snake abilities, particularly “how the hell does a tiny, tiny snake like this swallow a bird egg?”
Maritz told the Times that Jayne's study stands out because it upends traditional thinking when it comes to estimating the size of prey a snake can swallow.
“We’ve always just relied on proxies for snake gape,” Maritz told the Times. “We’ve said, ‘Well, gape is correlated broadly with head length, and so you can measure a snake’s head length and you can estimate its gape.’ And this study really shows that that’s not the case.”
