Thornback Ray - width to weight?
Had a doubleshot of Ray last night, measuring 62cm and 50cm across the wings. Did not have a scales with me so would anyone have an idea about the kind of weight they would have been? Even though the larger ray was only 12cm longer across the wings it seemed a lot heavier. The fight was similar to landing a bag of cement. I gestimate 11 1/2 lbs and 6 lbs.
