finger seaweed Eucheuma sp. and Kappaphycus sp. Family Solieriaceae updated Jan 13 Where seen? Small clumps of this sturdy branching seaweed is sometimes seen on our undisturbed Southern shores, very firmly attached to coral rubble near reefs. Features: Thick, hard 'fingers' about 8-20cm long that branch. Sometimes the 'fingers' are short and densely branched forming a bushy shape, others are longer and more sparsely branched. The tips are rounded. The surface is slimy and covered with bumps. Colours from pale golden to dark brown. These seaweeds may be Eucheuma species or Kappaphycus species both of the Family Solieriaceae. Human uses: Eucheuma and Kappaphycus species are widely farmed for carrageenan, a substance used as a thickening agent in manufactured food and other products. They are also eaten fresh or blanched in boiling water or made into a candy by boiling with sugar to form a gel. It is also used as livestock feed, an insect repellent and is believed to have medicinal properties |
