Classification
The Fucales include some of the more common
littoral
The littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore. In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely inundated), to coastal areas ...
seaweed
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of '' Rhodophyta'' (red), ''Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as ...

lamina
Lamina may refer to:
Science and technology
* Planar lamina, a two-dimensional planar closed surface with mass and density, in mathematics
* Laminar flow, (or streamline flow) occurs when a fluid flows in parallel layers, with no disruption betwee ...
. The lamina is often much branched and may include gas-filled bladders. Growth is by division of the apical cells.
They are oogamous - fusion between the small male gamete and the large female gamete.
