Types of Sea Moss:

  • Irish Moss (Chondrus Crispus) is one of the most popular types of sea moss and is usually spotted near the rocky coastlines of the North Atlantic. 
  • Jamaican Sea Moss (Eucheuma Cotton) grows in the Caribbean region.
  • Gracilaria (Gracilaria) Gracilaria can be found on the coasts of Asia and South America.
  • Kappaphycus Alvarez is commonly found in the coastal regions of Southeast Asia.
