description Porphyra umbilicalis Overview

Porphyra umbilicalis is a red seaweed (Rhodophyta) native to the North Atlantic, found attached to rocks in the intertidal and subtidal zones of European and North American coastlines. In Wales, it is traditionally harvested and boiled to produce laverbread, a dark, mineral-rich culinary dish notable for its high iron and protein content. The genus Porphyra is closely related to the species used to produce nori in Japanese cuisine, and P. umbilicalis is studied for its adaptations to intertidal stress, including desiccation and temperature fluctuations.
