Breakwater Dolphins Continuation of 20/6

A call from cliff's good lady sent me scurrying for my kit and a quick dash to the breakwater. The bottles were outside the breakwater seemingly just going back and forth. At first it looked like there were only two there but then we sighted a small calf with it's mother who just popped up out of nowhere and after a minute or two popped back out of the picture. The first two images below show the small calf 's fin alongside the mother and the other with it heading away alongside her.
