Fig. 1. Shape of the cormorant's body in three dimensions. (A) Schematic illustration (not to scale) of the apparatus used to measure the diameters of the cormorant carcass along the body's main axis.(B) Diameter of the width (lateral axis, solid rectangles) and height (dorso–ventral axis, empty circles). The x-axis represents the position along the body's main axis in % of body length (total body length = 85 cm). The diameters were used to calculate surface area, volume and added mass coefficients. The broken vertical lines mark the definition of the body excluding the neck and tail (trunk).
