Under The Skin…

We are into the bottlenose dolphin calving season up here in the Moray Firth and I often get asked about the discoloured, sometimes unsightly marks and blotches that often appear on young (and not so young) dolphins skin. These skin “lesions” as they are called appear to take on many different “types”, colours and shapes – both on adult dolphins and more noticeably on youngsters that have much paler skin. In the case of ID#1168, the not quite year old calf of ID#744 “Bonnie” in the photo below, he or she has lots of little markings here and there over all the body surface but there is a large grey patch on the rear flank that is more easily seen. This patch is already beginning to vanish compared to earlier photos as are other marks and so is the yellow staining on the dorsal fin and around the mouth. We often find that after a year or two the young dolphin looks much “cleaner” and we believe that skin lesions are not painful or irritating but are just something that these dolphins live with throughout their lives. Their skin has a tough environment to cope with – very cold water, differing salinities, sustaining tooth rake and bite marks from each other and collision damage plus bacterial infection too. Best Wishes, Charlie.
