Size Difference

Gray Whales (Eschrichtius gibbosus) in the Klamath River. Adult feemales grow up to 45 feet long and 35 tons; males are up to 35 feet and 17-30 tons. Calves are born at about 15 feet and 1 ton. This one is about 6 months old. From this photo, one can estimate that the mother is 1.9 times as long as the calf, but an accurate measurement has yet to be made.

Canon EOS 1D Mk4 camera and 70-200 f/2.8 L lens with ploarizer. 1/800 sec at f/2.8.
