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...

Lithothamnion corallioides is a calcified red alga associated with the northeast Atlantic and Mediterranean regions. It grows as a crust or as free-living calcareous fragments and is one of the species that can form maerl beds, often alongside Phymatolithon calcareum. Because its tissues contain sub...

Furcellaria lumbricalis is a red marine alga found in parts of the North Atlantic and Baltic Sea regions. It is a branched seaweed and is commercially important because it contains furcellaran, a polysaccharide with properties similar to carrageenan that can be extracted for use as a gelling or thic...

Gelidium amansii is a red alga of the order Gelidiales that grows in shallow coastal waters of East Asia.
