Science Question from a Toddler: Why is poop brown? In addition Synechococcus also contains zeaxanthin but no diagnostic pigment for this organism is known. These organisms do not possess chloroplast but they contain the different type of pigments. The marine snail Aplysia californica obtains its purple defensive ink exclusively from the accessory photosynthetic pigment r-phycoerythrin, which is found in the red seaweeds of its diet.
