This seaweed is highly variable in color and form. It is a delicate, branching red seaweed, which grows free or attached. It grows in depths of approx. 10 m, but most commonly less than 1 m (Littler et al. 2008. Submersed Plants of the Indian River Lagoon). It is a popular aquaculture species and is used primarily for the agar market and is gaining popularity for human consumption. Gracilaria makes for a great addition to soups, salads, ceviche and smoothies. It is used in a popular Caribbean drink known as seamoss or Irish moss drink.
