Baikal seals have unique teeth morphology compared to the closely related species.

Caption

Result of principal component analysis (PCA) on tooth morphology in Baikal seals and its relative species. Horizontal axis represents principal component 1 and vertical axis represents principal component 2. Ellipses represent 68% credible interval for each species (identified by different colors and symbols). Calculated mean values of each group are shown as larger symbols. Principal component loadings of each variable are represented by arrows.
