(Following question # 995974557.Bt)  The bright fluorescence (most commonly 
green, but other hues are also found) of many Anthozoa species (sea anemones, 
corals, sea pens) is assumed to provide protection from strong solar radiation, 
quite an important consideration in shallow tropical waters (from Matz et al, 
1999).  Could there be an energy related explanation like this for the rarity of 
red flowers, especially at high altitudes?
