One of the three subsurface "flipper" photos obtained in August 1972, during simultaneous and totally consistent sonar tracking of large unknown target, using an Edgerton elapsed-time strobe camera.

Subsurface "full body" photo obtained June, 1975. The upper part is interpreted to be a long neck and head extending from a bulky body.

Subsurface "full body" photo obtained June, 1975, of what is interpreted to be the head of a large animal. Had the fast sonar-triggered, elapsed-time strobe technique now being used been in operation in 1975, there would have been several photographs of the "head" taken at different angles. This may have aided identification.
