I think that anthocyanin is part of the pigment family called phycobilins,
which includes phycoerythrin. These are reddish pigments, allowing the red
algaes to absorb filtered wavelengths (blue & green) in fairly deep waters
in which red light has been extinguished. They also have various forms of
chlorophyll depending on depth; shallower algae have more chlorophyll, often
masking the phycobilins.
