Morphometry of the vestibular organ in neonate and adult African mole-rats Cryptomys species.

The dimensions (length and cross-sectional area) of the semicircular canal of the inner ear in Cryptomys (a rodent with long gestation, and altricial young with slow, extended postnatal growth) did not change after birth. This is further evidence for the relative morphometric postnatal stability of semicircular structures in mammals.
