Shell morphometry

Hello,

Here is part of the answer :

SL : Shell length (maximum in mm)
RW : Relative Weight = Shell Weight (SW, g) / SL (mm)
RD : Relative Diameter = Maximum Diameter / Aperture Height (AH)
PMD : Position of Maximum Diameter = Height of Maximum Diameter / AH
RSH : Relative Spire Height = (SL-AH)/SL
S : Aperture Shape = Aperture Wide = AW/Aperture Lengh (AL)

Happy Shelling,
DAVID
