MarLIN describes Laminaria digitata as a large, conspicuous kelp up to 2 metres long, usually seen at low water during spring tides on rocky shores.

According to MarLIN, the frond of Laminaria digitata is broad, divided into finger-like lobes, glossy, dark brown and without a midrib.

MarLIN states that Laminaria digitata is attached by freely branched root-like haptera that form a shallow, dome-shaped holdfast.
