''Laminaria digitata'' is a large brown alga in the family Laminariaceae, also known by the common name Oarweed. It is found in the sublittoral zone of the northern Atlantic Ocean. ==Description==
''L. digitata'' is a tough, leathery, dark brown seaweed that grows to two or three metres. The holdfast which anchors it to the rock is conical and has a number of spreading root-like protrusions called rhizoids. The stipe or stalk is flexible and oval in cross section. The blade is large and shaped like the palm of a hand with a number of more or less regular finger-like segments. This seaweed can be distinguished from the rather similar ''Laminaria hyperborea'' by being darker in colour and having a shorter stipe that does not easily snap when bent.〔(Laminaria digitata (Hudson) J.V.
