Introduction to the Rhodophyta The red "algae" Red algae are red because of the presence of the pigment phycoerythrin; this pigment reflects red light and absorbs blue light.Because blue light penetrates water to a greater depth than light of longer wavelengths, these pigments allow red algae to photosynthesize and live at somewhat greater depths than most other "algae". Coralline algae deposits protective calcium in its cell walls, and these encrusted algae act to cement together various corals, enhancing the reef's structure. Red algae are often shades of purple and red, and they can grow in the deep ocean. One adaption unique to red algae is a number of morphological adaptations that are extremely beneficial and are paramount to the organisms survival. It is a desirable algae to have in a saltwater aquarium and its growth is an indication of a properly matured marine fish tank.

When you think of algae, you likely imagine the slimy green growth in a dirty-looking aquarium. There are four thousand to six thousand species of red algae, and although some rhodophytes do inhabit freshwater (about fifty species), red algae are most common in tropical marine environments.

In traditional dishes, it is boiled with milk and rye flour or made into a relish and is commonly served with fish and butter.

A certain type of red algae called coralline algae can have a major role in boosting the stability of a coral reef. The red algae are characterized by reddish phycobilin pigments—phycoerythrin and phycocyanin—that mask the color of the chlorophylls.Most species grow near tropical and subtropical shores below the low-tide mark. If algae originated from a single strain, environmental evolutions have forced the adaptation into red, brown, yellow and green colour algae … Red algae, (division Rhodophyta), any of about 6,000 species of predominantly marine algae, often found attached to other shore plants.
