Distribution

''Gracilaria'' are found in warm waters throughout the world, though they also occur seasonally in temperate waters. It can not tolerate temperatures below . ''Gracilaria'' are found in all oceans except the Arctic Ocean, Arctic. Its center of diversity is the Western Pacific Ocean, Western Pacific, where it has been traditionally cultivated as a source of agar.

Use

''Gracilaria'' is used as a food in Filipino cuisine, Filipino, Cuisine of Hawaii, Hawaiian, Japanese cuisine, Japanese, and Korean cuisines. In Japanese cuisine, it is called ''ogonori'' or ''ogo''. In the Philippines, it is called ''gulaman'' and used to make Gelatin_dessert, gelatin. In Jamaica, it is known as ''Irish moss''. In Korea, it is known as ''kkosiraegi''.

''Gracilaria'' oligosaccharides with degree of polymerization 6 prepared by agarase digestion from agar-bearing ''Gracilaria'' sp. polysaccharides have been shown to be an effective prophylactic agent during ''in vitro'' and ''in vivo'' experiments against Japanese encephalitis viral infection. The sulfated oligosaccharides from ''Gracilaria'' sp. seem to be promising candidates for further development as antiviral agents.

In Japan, ''Gracilaria'' has been used to produce ''funori'' (), an agar-based glue, since the 17th century.

Aquarium trade

''Gracilaria'' commonly appears as a macroalgae for sale in the aquarium trade. It is a highly palatable algae to Acanthuridae, tangs and many other herbivorous fish, and its nutrient uptake ability makes it a suitable choice for a Refugium (fishkeeping), refugium.

Ecology

''Gracilaria'' are susceptible to infection by the Parasitism, parasitic oomycete ''Pythium porphyrae''. Reproduction by ''Gracilaria gracilis'' is supported by ''Idotea balthica'' – the first known case of an animal helping algae reproduce.
