Beach puffs are congregations of a single cellular micro-organism that evolved from testudohexapodia acta. In order to produce and distribute spores, colonies of beach puff microbes gather together and form small spheroid structures in the moist sands of Sagan's beaches. These structures are at most the size of a ping pong ball. The formation of beach puffs occurs periodically, three times in a Saganian year, and each blooming lasts for only 15–20 days. Beach puffs gain most of their energy through a type of photosynthesis using a blueish photosynthetic pigment called phaeophytin.
