Despite their name, red algae can vary in color from bright green, soft pink, resembling brown algae, to shades of red and purple, and may be almost black at greater depths. [ 12 ] [ 13 ] Unlike green algae, red algae store sugars as food reserves outside the chloroplasts as floridean starch , a type of starch that consists of highly branched ...

The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green. Coralline algae play an important role in the ecology of coral reefs. Sea urchins, parrot fish, and limpets and chitons (both mollusks) feed on coralline algae.
Polysiphonia, known as red hair algae, [1] is a genus of filamentous red algae with about 19 species on the coasts of the British Isles [2] and about 200 species worldwide, [3] including Crete in Greece, Antarctica and Greenland. [4] [5] Its members are known by a number of common names. [note 1] [4] It is in the order Ceramiales and family ...
The thallus features a main axis with an apex of varying shapes (straight, curved, tendril or bifurcated). Various forms of branching occur, with the irregular type being most common, with dichotomous or lateral branching occurring in some species. Thallus color is highly variable, with yellow, green, pink, red, brown and black being observed.
Rhodomelaceae is estimated to be the largest red algae family, with about 125 genera and over 700 species. [1] Included taxa
Karenia brevis, or K. brevis for short, is the blood red algae to blame. On Monday, the Florida Fish and Wildlife Conservation Commission said the bloom was a whopping 90 miles long, 60 miles wide ...
It is the presence and relative abundance of chlorophyll that gives plants their green color. All land plants and green algae possess two forms of this pigment: chlorophyll a and chlorophyll b. Kelps, diatoms, and other photosynthetic heterokonts contain chlorophyll c instead of b, while red algae possess only chlorophyll a. All chlorophylls ...
