Red Algae vs. Brown Algae: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 14, 2024
Red Algae is primarily marine, often found in deeper waters. Brown Algae mostly found in shallower, coastal waters.

Key Differences

Red algae, known scientifically as Rhodophyta, are predominantly marine and thrive in deeper, sometimes tropical waters. Brown algae, belonging to the Phaeophyceae class, are more commonly found in shallow, coastal environments, often in cooler regions.

The pigmentation of red algae comes from phycoerythrin, giving them their distinctive color and allowing them to photosynthesize in deeper waters. In contrast, brown algae possess a pigment called fucoxanthin, which gives them their brownish color and is effective in absorbing light in shallower waters.
