Data were obtained by subtraction of the movement of the rod alone from the movement of the shell plus rod assembly. These data measured in millimeters of displacement were transformed into force data for each shell in the four taxa of melanopsids. This was done at several different rates of water flow through the apparatus. Using spreadsheets, the force data and other parameters such as maximum shell length and projected profile length were used to calculate Reynolds number and the drag coefficient.
