Most predators leave bones behind when they eat, but Burmese pythons swallow their prey whole\u2014skeleton and all. Now scientists have discovered how these massive snakes accomplish this feat: they’ve evolved specialized intestinal cells that capture excess calcium and phosphorus from dissolved bones, preventing potentially fatal mineral overload.<\/p>\n

The discovery, published in the Journal of Experimental Biology<\/a>, reveals a previously unknown cell type that functions like microscopic waste management centers. These cells create calcium-rich particles and store them in internal crypts before expelling them as waste.<\/p>\n

The Bone-Dissolving Challenge<\/h2>\n

“We wanted to identify how they were able to process and limit this huge absorption of calcium through the intestinal wall,” explains Dr. Jehan-Herv\u00e9 Lignot, a Professor at the University of Montpellier who led the research.<\/p>\n

When pythons digest entire skeletons, massive amounts of calcium and phosphorus flood their intestines. Too much calcium in the bloodstream can prove lethal, yet snakes fed boneless prey develop calcium deficiencies. The research team wondered: how do pythons extract what they need while avoiding toxic overload?<\/p>\n

Using light and electron microscopy, the scientists analyzed python intestinal cells after feeding the snakes three different diets: whole rodents, “boneless prey,” and boneless rodents injected with calcium carbonate supplements.<\/p>\n

Microscopic Mineral Factories<\/h2>\n

The analysis revealed extraordinary cellular architecture. Unlike typical intestinal cells that absorb nutrients, these specialized cells are narrow with short microvilli and feature an internal fold forming a crypt\u2014essentially a storage chamber.<\/p>\n

“A morphological analysis of the python epithelium revealed specific particles that I’d never seen in other vertebrates,” Lignot notes. These particles, composed of calcium, phosphorus, and iron, accumulate within the cellular crypts like mineral deposits.<\/p>\n
