Fig. 2 Anterior, lateral, and ventral views of the myliobatid ray models designed for hydrodynamic testing. (A) Model with a dihedral angle of 6.4° (DM1). Note the cavities made on all models to insert the biologger, the tether, and the tail. (B) Model with a dihedral angle of 35.9° (DM2). (C) Model with a dihedral angle of 80° (DM3). (D) Model AM with an anhedral angle of 80°. All models have disc widths of 15 cm and a Bl of 9.5 cm. The position of the COM ( ) is approximated.

"During swimming, #myliobatids often exhibit gliding behavior, a passive locomotion mode when active flapping ceases and the pectoral fins are maintained in a static position..."
