Just like oarweed, sea belt also looks like long leathery ribbons. However, the fronds are lancet-shaped with wavy edges. Roots that cling to stones and shells give the seaweed a sturdy base under water. When wet, the leaves feel slippery due to a kind of mucus. When dried up, a white powdery 'sugar' forms on its fronds, giving sea belt its nickname sugar kelp. In fact, this seaweed is used as a natural sugar substitute.
