Otters are secretive creatures, quite common but rarely seen. The best you can hope for are signs that they are about.
Seals, on the other hand, are easy to watch, but if you want to see more than a head bobbing above the water, you need to know where and how to look. Tony goes seal-watching and, for the first time in his life, observes common seals swimming up the saltmarsh creeks and hauling themselves out on to the mud flats.
