Flatworms

Platyhelminthes

Platyhelminthes (Flatworms) is a phylum of animals. There are 18089 species of Flatworms, in 3107 genera and 355 families. This phylum has been around since the cambrian series 2 epoch. It includes groups like Flukes and Cestodes. They have sexual reproduction. They rely on ciliary gliding to move around.

Definition: Capable of creating a new organism by combining the genetic material of two gametes, which may come from two parent organisms or from a single organism, in the case of self-fertilizing hermaphrodites.

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.
