Absolute levels of shape variance for the whole inner ear as well as the separate structures for the four groups (top) and differences of shape variance (SV) levels between the four groups for the whole bony labyrinth, only the cochlea, only the semicircular canals and the lateral, the anterior and the posterior semicircular canal separately (red = significant value).
