Irish Moss, or Chondrus crispus, is a species of red algae found abundantly along the rocky Atlantic coasts of Europe and North America. This seaweed thrives in the intertidal and shallow subtidal zones and is characterized by its fan-shaped, cartilaginous fronds. It is heavily harvested because it...
Chondracanthus chamissoi is a species of red macroalgae widely distributed along the Pacific coast of South America, particularly in Peru and Chile. Known locally as yuyo, this seaweed grows in subtidal and lower intertidal rocky zones and is harvested both from wild populations and through structur...
*Chondrus crispus*, widely known as Irish moss, is a species of red algae that grows abundantly along the rocky coastal regions of the North Atlantic Ocean. It is heavily harvested for its rich concentration of carrageenan, a gelatinous polysaccharide that serves as a highly effective thickening and...
Sarcothalia crispata is a species of red macroalgae in the order Gigartinales, native to the southeastern Pacific coast. It is distributed along the coastlines of Peru and southern Chile, where it grows in subtidal marine environments. The species is harvested for its cell wall polysaccharides, whic...
Hypnea valentiae is a species of red macroalgae belonging to the family Cystocloniaceae. It is widely distributed across tropical and subtropical marine environments, including the Indo-Pacific and Atlantic coasts. The alga typically features cylindrical, irregularly branched thalli that form dense,...
Solieria chordalis is a species of red marine alga belonging to the family Solieriaceae. It is distributed along the Atlantic and Mediterranean coasts, where it typically inhabits shallow subtidal waters. The seaweed is characterized by its gelatinous, cord-like thallus and is harvested on a commerc...
Kappaphycus alvarezii is a large tropical red seaweed cultivated extensively as a commercial source of kappa-carrageenan. Originally associated with the maritime region of Southeast Asia, it is now farmed in warm coastal waters in several countries, commonly by attaching vegetative cuttings to ropes...
Eucheuma denticulatum is a species of red alga native to the tropical waters of the Indo-Pacific region. It is recognized as one of the most commercially significant cultivated seaweeds globally due to its high concentration of iota carrageenan, a thickening and gelling agent. The species is extensi...
Solieria robusta is a species of tropical red macroalgae found in the warm waters of the Atlantic and Indo-Pacific oceans. It belongs to a genus of seaweed extensively studied for its ability to produce carrageenan-type sulfated polysaccharides, which are widely used as gelling and thickening agents...
Red alga native to the Atlantic coast of North America and the Caribbean, studied for its carrageenan-like sulfated polysaccharides with potential commercial applications.
Red alga (Gigartinales) distributed across the Mediterranean Sea and adjacent Atlantic coasts, forming dense, spiny tufts on rocky intertidal and subtidal substrates.
Large red alga native to subantarctic and southern South American coasts, commercially harvested in Chile and Argentina as one of the primary sources of carrageenan.
Tropical red alga native to Southeast Asia and cultivated extensively across the Indo-Pacific and East Africa as one of the world's leading commercial sources of kappa-carrageenan.
Red alga common on North Atlantic rocky shores, notable for a heteromorphic life cycle in which its crustose phase was long classified as a separate genus, Petrocelis.
Red alga native to Pacific coasts of the Americas, notable for its iridescent heart-shaped thallus and use as a source of carrageenan in food and industrial applications.
Tropical red alga of the Indo-Pacific, one of the few natural sources of beta-carrageenan, a structurally distinct hydrocolloid that forms gels under different conditions than kappa-carrageenan.
Red alga (family Gigartinaceae) of the Mediterranean and eastern Atlantic, a source of carrageenan whose taxonomy has undergone multiple revisions since its original description.
Tropical and subtropical red alga distributed across Atlantic, Pacific, and Indian Oceans, commercially harvested at large scale as a primary source of kappa-carrageenan hydrocolloid.
Red alga found across Indo-Pacific and Atlantic coastlines, closely related to Hypnea musciformis and similarly valued as a regional source of carrageenan for food processing.
