In the online version of the original publication [1], Figs. 2, 3 and 4 were switched. Figure 2 should show the photo of female Steller sea lion identified as = 908, Fig. 3 should show the X-ray radiograph, and Fig. 4 should show the surgery in progress. The online version was updated to rectify this error.
