PLANARIA: The cross-eyed flatworm, Planaria, is both scavenger and predator depending upon opportunity. Observations show food-seeking behavior, the flatworm’s feeding method, locomotion (produced by a carpet of cilia), internal anatomy, and reproduction through the remarkable process of regeneration. |
