Needed Images of Whale and Dolphin Flippers- I am examining the hydrodynamic morphology of dolphin and whale flippers. Specifically I need photographs of flippers in which the full planar surface (dorsal or ventral sides) is facing the camera and the whole flipper is shown from the insertion of the flipper with the body to the flipper tip. The photograph needs a scale of known length in the image. It is required that measurements of body length be provided and also if possible a measurement of body mass. Please send images with your name and contact information by email (ffish@wcupa.edu). Slides and photographs can also be sent to:  Dr. Frank Fish, Dept. of Biology, West Chester University, West Chester, PA 19383; phone- 610-436-2460.
