Abstract : The size, length, and shape of the cochleas are compared in different mammalian species, with the use of graphic cochlear reconstructions. The ratio between the size of the cochlea and that of the skull generally decreases when the skull size increases. In other words, the size of the cochlea in small mammals is considerably larger. The number of cochlear turns increases when the cochlea protrudes into the well-pneumatized mastoid bulla instead of being embedded in the thick otic capsule. (Author)
