Seaweed: The Pearls of the Sea

Seaweed refers to several species of macroscopic, multi-cellular, marine algae. Macroalgae, which are found in the Divisions Chlorophyta, Phaeophyta and Rhodophyta are commonly called seaweeds because of their size, multicellular construction, and attachment to firm substrata. The three major divisions of seaweeds contain taxa that have more fundamental (e.g. cytological, …

Toxic Algae & Human Health

Algal toxins are toxic substances released by some types of algae when they are present in large quantities (Blooms) and decay or degrade. These toxins are called ‘Phycotoxins’ (from Greek, phykos, “seaweed”; and toxikon, “toxin”). They are usually complex allelopathic metabolites produced by algal secondary metabolic pathways. These metabolites are (in most cases) not harmful to …
