The Broad Umbrella Term for Sea Moss
Despite its common use as a single name, 'sea moss' functions as a broad, catch-all term for various red algae species. The most well-known species associated with the name come from two distinct regions and climates: the cool waters of the North Atlantic and the warmer, tropical waters of the Caribbean. This geographical and biological diversity is the primary reason for the variety of names attributed to sea moss. Understanding this distinction is crucial to navigating the world of sea moss products and their origins.
Irish Moss: The Atlantic's Chondrus crispus
The most famous of all sea moss varieties is Irish moss, scientifically known as Chondrus crispus. This variety grows abundantly along the rocky coastlines of the Atlantic, particularly in Europe and North America. Its historical use in Ireland is well-documented, especially during the Great Famine of the 19th century, when it served as a vital source of nutrition. Irish moss is known for its stiff, cartilaginous, and frilly appearance. Its color can range from a greenish-yellow to a dark purplish-brown. This variety is a rich source of the polysaccharide carrageenan, which has been historically harvested and used as a thickening agent.
Other Common Names for Chondrus crispus
Chondrus crispus also goes by other names rooted in its history and origin. Among them are:
- Carrageen: A popular name, derived from the Irish word carraigín, meaning 'little rock'.
- Carrageen Moss: An expansion of the name that is widely recognized.
- Jelly Moss: This name references the gelatinous substance it produces when boiled.
- Goémon blanc: The French name, also used to refer to this specific species.
Caribbean and Tropical Varieties: Gracilaria and Eucheuma
While Chondrus crispus dominates the North Atlantic, other types of sea moss thrive in warmer, tropical waters. The most common of these include species from the genera Gracilaria and Eucheuma. These are often cultivated in regions like the Caribbean, Southeast Asia, and South America, and are commonly referred to as Caribbean or Jamaican sea moss. Unlike the thick, curly Atlantic variety, Gracilaria often has a thinner, more stringy or tubular appearance.
Notable Caribbean and Tropical Names
- Jamaican Sea Moss: A common name for the Gracilaria species found in the Caribbean. It is a key ingredient in traditional Caribbean beverages and tonics.
- Gusô: A Filipino name for Eucheuma cottonii, a related red algae.
- Agar-agar: A gelling agent extracted from Gracilaria and similar species, widely used in Asian cuisine.
Comparison of Sea Moss Types and Their Names
| Attribute | Chondrus crispus (Irish Moss) | Gracilaria Species (Caribbean Sea Moss) |
|---|---|---|
| Common Names | Irish Moss, Carrageen Moss, Carrageen, Jelly Moss | Jamaican Sea Moss, Caribbean Sea Moss, Agar-agar source |
| Habitat | Cold Atlantic waters off North America and Europe | Warm, tropical waters of the Caribbean, Asia, South America |
| Appearance | Thick, dense, cartilaginous, and fan-shaped | Thinner, tubular, more delicate fronds |
| Origin | Wild-harvested, with some aquaculture | Widely cultivated, but also wild-harvested |
| Consistency | Often produces a more robust gel due to its unique carrageenan content | Creates a smoother, softer gel; also processed into agar |
Species vs. Extract vs. Product
A key point of confusion for many lies in the distinction between the species itself, the extract, and the final product. Carrageenan is a prime example. While it is extracted from various red seaweeds, including Chondrus crispus and Gracilaria, the term 'carrageenan' refers specifically to the gelling agent, not the plant itself. This food additive (E407) is used to thicken and stabilize products like dairy and processed foods. Another consideration is the finished product, such as sea moss gel or powder, which can be made from any number of species, adding another layer to the name game. Always check the product's label to determine the exact species or origin.
The Role of Cultural Context
The naming conventions for sea moss are deeply intertwined with cultural traditions and uses. The Irish name 'Carrageen' reflects centuries of local use, while the Jamaican 'Irish moss' beverage speaks to its regional significance in the Caribbean. In Japan, the name 'Hana Tsunomata' is used for a cultivated variety of Chondrus crispus. This global use highlights the plant's diverse applications and the many names it has accrued over time.

Conclusion
In summary, there is no single answer to what else is sea moss called, as the name changes based on the specific species, origin, and cultural context. The most prominent variations are Irish moss (Chondrus crispus) from the cold Atlantic and Caribbean sea moss (species like Gracilaria) from tropical waters. Consumers should be aware of these distinctions, particularly when purchasing products, to ensure they are getting the variety they intend. Whether you call it carrageen, gusô, or simply sea moss, this versatile red algae has a rich history and a global presence under many different titles.
