Green algae

Limu wāwaeʻiole — literally "rat's foot" — is a soft, branching green algae that grows in shallow tidepools and on protected reef flats throughout the Hawaiian Islands.

It was a staple of the traditional Hawaiian diet, eaten fresh or salted and often pounded with kukui nut and chili pepper as a relish (ʻinamona) for fish and poi.

Today it remains one of the most commonly gathered limu, but stocks have declined in some areas due to pollution and overharvesting. Traditional gathering practices — taking only what you need and leaving the holdfast — are essential to its survival.
