Nature documentary. An underwater journey to see the wildlife treasures that lie beneath the waves of the Channel Islands. Here, at the southern most tip of the British Isles, the waters are home to a rich variety of marine life from curious cuckoo wrasse, to soft corals and cuttlefish. Underwater film-maker Sue Daly gives a personal insight into her aquatic backyard as she dives amongst the kelp, colour and secret anemone caves.
