Two populations:
same teeth?

The Scyliorhinus canicula populations exhibit body size differences at sexual maturity that follow a latitudinal gradient. Shark teeth replace lifelong, and tooth shapes are modified along the ontogeny and the increasing body size. We wish to discriminate teeth from two S. canicula populations (from the North Atlantic Ocean and North Mediterranean Sea) with distinct body lengths at sexual maturity. We use 3D geometric morphometric and machine learning methods (Random Forests) to classify teeth from both sexes and along three ontogenetic stages.

Methods: 3D Geometric morphometrics and Random Forests
