Intraspecific variation of cochlear morphology in bowhead and beluga whales
The Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...
