Dumontia contorta

Seaweeds don’t have roots- they have what is called a “holdfast”, a term shared with coral, sponges and all sorts of crazy ocean flora. The holdfast varies in shape and size depending on the species and what it’s attached to. Unlike most roots on the surface, the holdfast doesn’t absorb nutrients and is simply used to hold the organism in place.
