Isaurus tuberculatus "Snake Polyp"
Snake Polyps (Isaurus tuberculatus) are long brown polyps that attach to a hard surface like rockwork. During the day, they look like brown worms that extend from the base. At night, they extend feather-like feeding apparatus into the water to feed on zooplankton like Daphnia, Cyclopeeze, copepods and similar items. They are also photosynthetic and receive must of their nutrition from the algae in their tissues, but supplements at night will help the colony to grow and expand.
