Blue tips are red algae's red flags

Some red algae exhibit structural color that gives their growth tips a blue hue and the rest of their bodies including their fruiting structures a white hue. Moreover, since the color-producing structures are located together with anti-herbivory chemicals, the discovery further suggests that red algae use colors for inter-species communication.
