Raw cochleae measurement data
This is required to build odontocete-data-linear.csv.
- specID - Specimen accession number
- taxon - Species binomial
- side - Side of the animal the cochlea came from (Right or Left)
- nTurns - Number of turns of the cochlear canal
- volume - Volume (in mm^3)
- cochleaHeight - Cochlea height (mm)
- cochleaWidth - Cochlea width (mm)
- canalLength - Canal length (mm)
- sslLength - Secondary spiral lamina (SSL) length (mm)
- sslExtent - % of extent of SSL (SSL length/cochlear canal length)*100)
- basalRatio - Basal ratio (cochlear height/cochlear width)
- axialPitch - Axial pitch (cochlear height/number of turns)
- W2 - Width of basal turn perpendicular to cochlear width
- ITD - Interturn distance (maximum distance between turns of the cochlea)
- maxRadius - Maximum radius of spiral ganglion (this is omitted from analyses as we do not have records for all specimens)
- FC - Surface area of fenestra cochlearis in (mm^2)
