Red Algae

Google Gemini - Created with AI prompt (This page needs scrutiny)

Red algae (Phylum Rhodophyta) are a massive group of mostly marine seaweeds. They are distinguished from green and brown algae by the presence of the pigment phycoerythrin, which reflects red light and absorbs blue light. This adaptation allows some red algae to grow at greater depths than other seaweeds.

In British Columbia, they range from delicate, filamentous "sea mosses" to calcified "coralline" algae that resemble rocks. Economically, they are the most valuable seaweeds, serving as the source for Agar and Carrageenan (industrial thickeners). For the forager, this group contains highly prized edibles like Nori (Porphyra) and Dulse (Palmaria). Unlike brown algae, red algae generally do not have toxic look-alikes, though many are too tough or calcareous to be palatable.
