The Secret Language of Crocodile Scales
scientists have long been intrigued by the unique structure and growth of crocodile jaw scales.More than Just Skin Deep
The scales on a crocodile’s head aren’t just for show. They play a crucial role in the animal’s growth and progress. Understanding how these scales grow and change can provide valuable insights into the complex biology of these ancient reptiles.The Fascinating Scales of Crocodiles
Crocodiles are instantly recognizable,not just for their powerful jaws and imposing size,but also for their distinctive,wrinkly snouts.Unlike the smooth scales found on many reptiles, crocodile skin is a complex marvel of nature, with patterns that have captivated scientists for years.
These scales are unlike anything seen in other reptiles, differing significantly from the patterns of hairs, feathers, and scales on their evolutionary cousins. What makes crocodile scales so unique, and how do they develop this intriguing texture?
Researchers are continuously working to unravel the mysteries behind crocodile skin, seeking to understand the biological processes that create such a distinctive and fascinating feature.
The Mysterious Sculpting of Crocodile Head Scales
Scientists at the University of Geneva’s Laboratory of Artificial and Natural Evolution (LANE) have made a fascinating discovery about crocodile head scales. These unique scales, distinct from the typical reptile scales found elsewhere, don’t develop from thickened skin areas called placodes. Rather, their formation is governed by a surprisingly intricate mechanical process. This research, led by biologist Michel Milinkovitch, sheds new light on the remarkable diversity and complexity of reptilian scale development.## The Science Behind a Crocodile’s Grin

**NARRATOR:** Biologist Michel Milinkovitch at the University of Geneva’s Laboratory of Artificial and Natural Evolution was captivated by the peculiarity of crocodile heads.
**MICHEL MILINKOVITCH:** * [SOUNDBITE from [1]]I was so surprised by the pattern of very irregular scales on the head of the animal, very different on the left and on the right. And also, many of the edges are, like, incomplete.*
**NARRATOR:** Unlike the smooth scales found on other reptiles, crocodile scales are formed through a complex mechanical process, not simply from thicker skin.This revelation sheds new light on the evolutionary history and unique development of these ancient creatures.
