Freshwater Flatworm (Planarian)

Natural Habitat

Slow-moving freshwater environments such as ponds, streams, and lakes, typically found under rocks, logs, or debris.

Diet & Feeding

Carnivorous and scavenger; feeds on small invertebrates like water fleas, tiny worms, and organic debris using a protrusible pharynx.

Behavior Patterns

Photophobic (retreats from light), exhibits slow gliding movement using microscopic cilia, and possesses remarkable regenerative capabilities, able to regrow entire body parts from fragments.

Risks & Benefits

Harmless to humans; serves as an important indicator of water quality and a model organism for biological research on regeneration and stem cells.
