Kelps include some the largest seaweed species. Predominantly subtidal they can form underwater forests and are recognized by their long flexible stipe, flat frond and large holdfast.
Below are images of kelps you may encounter at the low water mark and whilst snorkeling in the shallow subtidal around the UK:
Laminaria including Laminaria digitata , Laminaria hyperborea and Laminaria ochroleuca are the typical 'kelps'. They have a holdfast, stipe and a large flat frond that is divided into strips. Laminaria occur from the low water mark into the subtidal.

|Many species can be found within the hold fast of Lamiaria species, including Oysters (Anomiidae) and Starfish (Henricia oculata).|
|Saccorhiza polyschides is recognizable by the folds on the stipe close to the holdfast and occurs subtidally.|
