Morphology of the vertebral centra in dolphins from the southwestern South Atlantic: A 3D morphometric approach and functional implications
Abstract In dolphins, centrum shape is one of the features that allows determination of stable and flexible regions in the vertebral column. The Commerson's ( Cephalorhynchus commersonii n = 37), Peale's ( Lagenorhynchus australis n = 24), dusky ( Lagenorhynchus obscurus n = 29), and hourg...
