Marine region

A seaweed dish with a name of its own: jukut bulung boni. In Bali, grape caulerpa is recorded among the ingredients used in this traditional preparation, as well as in certain forms of rujak. Indonesian culinary literature distinguishes several edible Caulerpa species. The familiar expression “sea grapes” covers more than one seaweed, even when their small rounded branches look remarkably similar.

WHAT DOES IT LOOK LIKE?

Grape caulerpa (Caulerpa cylindracea) bears upright green axes lined with ramules, short branches swollen into club shapes. These small structures point upwards.

A stolon, the creeping axis, connects the upright parts. Fine rhizoids, attachment filaments rather than true roots, anchor it to the surface.
