Ceramiales

Ceramiales is an order of red algae, a group of multicellular algae that are typically found in marine environments. The order is named for the type genus Ceramium, a common genus of red algae. Ceramiales are a diverse group of algae, with over 700 species described in the literature. These species are found in a variety of habitats, including rocky shores, tide pools, and deeper water environments. Some species are also found in freshwater habitats.

Common Names

Ceramiales are sometimes called "feather algae" or "coralline algae," although these names are not specific to this order.

Characteristics

Ceramiales are characterized by their complex life cycles, which often involve alternating generations of haploid and diploid individuals. They are also known for their distinctive branching patterns, which can be quite intricate. Most Ceramiales species produce carrageenan, a polysaccharide used in food production and other industries. Some are also known to produce other commercially valuable chemicals.

Environments

Ceramiales are found in a wide range of marine environments, including:

  • Rocky shores
  • Tide pools
  • Shallow water reefs
  • Deeper water environments

Some species are also found in freshwater environments.
