The kelp is attached to the substrate by means of a holdfast, which appears similar to the branching roots of a tree. Between the light brown branching processes (haptera) there is usually a wide range of invertebrate

 animals taking advantage of the protected micro-environment. Above the holdfast is a long, flexible stalk or stipe, much darker in colour. Finally, there is a much divided terminal blade, yellowish brown and often crinkled and frayed. The kelp is never completely exposed at low tide.
