Vertebrae organization
in skates

Vertebral column
Fidji Berio

Vertebrates are a major extant clade of organisms that share the presence of a vertebral column. This structure, however, varies in number of vertebrae, shape, size, and organisation of vertebral elements.

The vertebral column of skates (and more broadly of cartilaginous fishes) is still poorly known. In this project, we investigate the detailed organisation of the vertebral column in Amblyraja radiata to better understand the evolution of this structure in vertebrates.

Methods: microCT scans, clear and stain double coloration

Working with: Richard Cloutier, Yann Bayle, Olivier Larouche, and Cyrena Riley
