Fucales is an order in the Phylum Phaeophyta or Brown algae. Members of this order are fucoids. The list of families (see box at right) in Fucales, as well as additional taxonomic information on algae, is publicly accessible at Algaebase. [1] ^[1] In scientific classification used in biology, the order (Latin: ordo, plural ordines) is a rank between class and family (termed a taxon at that rank). ... For the linguistic term, see Phylum (linguistics). ... Orders Dictyotales Desmerestiales Fucales Laminariales (kelps) etc. ... The Heterokontophyta (Phaeophyta or brown algae, singular: brown alga) is a large group of mostly marine multicellular algae, including many seaweeds of colder Northern Hemisphere waters. ...

The Class Phaeophyceae is included within the Division Heterokontophyta. This name comes from the Greek word phaios meaning "brown" and phyton meaning plant.^[2] They include some of the largest plants in the sea, some however are small and fine in structure.

Classification

The Class Phaeophyceae is devided into the following orders (Hoek, 1995). ^[3]

• Ectocarpales

• Sphacelariales

• Syringodermatales

• Dictyotales

• Scytosiphonales

• Cutleriales

• Dictyosiphonales

• Chordariales

• Sporochnales

• Desmarestiales

• Laminariales

• Fucales **Fucus

• Durvillaeales

• Ascoseirales

The Fucales include some of the more common littoral seaweeds and the members of the order have the typical seaweed construction of a holdfast, stipe and lamina. The lamina is often much branched and may include gas filled bladders. Growth is by division of the apical cells. Species F. serratus F. vesiculosus Fucus is a genus of seaweed that lives in the intertidal zones of rocky shores. ... A littoral is the region near the shoreline of a body of fresh or salt water. ... Ascophyllum nodosum exposed to the sun in Nova Scotia, Canada Dead Mans Fingers (Codium fragile) off Massachusetts coast For the band, see; Seaweed (band) For the rock musician, see; Seaweed (musician) Seaweeds are any of a large number of marine benthic algae. ... A holdfast is a rootlike plant structure that anchors a seaweed. ... In botany, a stipe is a supportive structure that may be stem-like, as in seaweed, or a true leaf stem, as in ferns. ... A Lamina in the algae is a generally flattened structure which typically forms the principal bulk of macroscopic plants. ... A bladder is a pouch or other flexible enclosure with waterproof or gasproof walls. ...

They are oogamous where there is fusion between the small male gamete and the large female gamete.

As their general name suggests their pigmentation is brown. All species are multicellular. Full details of the characteristics are complex and consist of details of the flagella, shape of the chloroplasts, structure of the cell walls and details of the life-cycle. ^[3] Natural Ultramarine pigment in powdered form. ...

Numbers

There are about 1,500 - 2,000 species of brown seaweeds world-wide.^[4]
