Figure 2


Fig. 2. (A) Schematic drawing of the bending apparatus used for determining structural stiffness (EI, Nm2). The thick gray line represents the central axis of the animal and the triangle at the bottom of the image represents the flukes. (B) Actual image of the bending apparatus as seen from above. The specimen shown here is a Grampus griseus (WAM 570, total length 215 cm), positioned for lateral deformations. The animal is immobilized with two ratchet tie-downs cranial and caudal to the pectoral fin. The central axis of the animal is marked with zinc oxide dots, while the center of the dorsal fin, the anus and the mid-peduncle are marked with horizontal white lines.
