Polyposthia similis Bergendal 1893

Polyposthia similis is a species of flatworms in the family Polyposthiidae. Individuals can grow to 25 mm. They rely on ciliary gliding to move around.

URI: http://eol.org/schema/terms/ciliary_gliding
Definition: a type of locomotion in which an animal moves on a secreted layer of mucus, propelled by the beating of cilia. It is characteristic of small, soft-bodied invertebrates.

stemmata
- URI: http://purl.obolibrary.org/obo/UBERON_0000046
- Definition: Eye-spots which may be set into a pit to reduce the angles of light that enters, to allow the organism to deduce the angle of incoming light. Lens-like structures may be present, but stemmata, unlike lens eyes, cannot form an image, either for lack of refractive power or retinal resolution.
