| Species | |
Haematococcus is a genus of algae in the family Haematococcaceae. Members of this group are a common cause of the pink color found in birdbaths.[1] One of the most notable species of Haematococcus is H. pluvialis, which is used in cosmetic products due to its production of astaxanthin, a powerful antioxidant carotenoid, under stress conditions.

Flagellate stage
When stressed, this green microalgae, Haematococcus pluvialis, degrades chlorophylls and accumulates a strong red antioxidant, the carotenoid astaxanthin
