Dive down past swirling green ribbons to rocks where kelp strikes its hold. Denizens of cooler seas, kelps are a group of seaweeds better appreciated by swimmers than rock poolers, as their beauty unfurls in deeper water. Cuvie (Laminaria hyperborea) is the kelp that skirts Britain and Ireland along their rocky shores. Growing in water from 1m to 47m deep, cuvie is only visible to land lubbers at low tides when its rigid stipes emerge upright from the water while its fronds are crumpled in the shallows.
