Ogonori (Gracilaria spp.), also called ogo or sea moss, is a type of edible seaweed eaten along the coasts of Japan, Southeast Asia, Hawaii, and the Caribbean. Ogonori is typically eaten cold and is a source of the thickener agar.
The potential of Gracilaria as a research subject for genomic study has hardly been explored.
In Hawaii, people use it in Poke.
