Planaria are small flatworms from the phylum Platyhelminth. They are found in unpolluted lakes, ponds, rivers and many other aquatic environments.
While some flatworms can be parasitic, planaria eat decaying matter and smaller animals. Planaria eat by extending their pharynx out and sucking up food. Here they can be seen eating boiled egg yolk.
Planaria are studied for their remarkable regeneration abilities. If you cut a planarian worm into several pieces, each piece will regenerate into a new worm.
The magnification is seen in the bottom right hand corner of each shot.
