Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon and producing at least 50% of Earth's oxygen. [3] Natural seaweed ecosystems are sometimes under threat from human activity.
The elkhorn sea moss varies in size, weight, and age. It is a dark greenish-brown hue and can sometimes be deep purple. The moss is cylindrical in shape throughout the seaweed. Its diameter averages 1.526 mm when dried. [1] Near the base of the seaweed, its average length is from 1 mm to 17 mm and 1 mm to 2 mm in diameter.
The singular alga is the Latin word for 'seaweed' and retains that meaning in English. [13] The etymology is obscure. Although some speculate that it is related to Latin algēre , 'be cold', [ 14 ] no reason is known to associate seaweed with temperature.

“Seaweed comes in multiple colors and consists of a myriad of species that provide a range of exciting skin benefits: firming, brightening, moisturizing, exfoliating… and more!” Palmer adds ...
Seaweed is a moderate source (less than 20% DV) of niacin, iron, and zinc. Seaweed has a high content of iodine , providing a substantial amount in just one gram. [ 19 ] A 2014 study reported that dried purple laver ("nori") contains vitamin B12 in sufficient quantities to meet the RDA requirement (Vitamin B12 content: 77.6 μg /100 g dry ...
Eucheuma, commonly known as sea moss or gusô (/ ɡ u ˈ s ɔː ʔ /), is a rhodophyte seaweed that may vary in color (purple, brown, and green). Eucheuma species are used in the production of carrageenan, an ingredient for cosmetics, food processing, and industrial manufacturing, as well as a food source for people in the Philippines, Caribbean and parts of Indonesia and Malaysia. [1]
A common seaweed used for manufacturing the hydrophilic colloids to produce carrageenan is Chondrus crispus (Irish moss), which is a dark red, parsley-like alga that grows attached to rocks. Gelatinous extracts of C. crispus have been used as food additives since approximately the fifteenth century. [ 3 ]
