Individual adult digeneans are of a single sex, and in some species slender females live in enclosed grooves that run along the bodies of the males, partially emerging to lay eggs. In all species the adults have complex reproductive systems, capable of producing between 10,000 and 100,000 times as many eggs as a free-living flatworm.

Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. [ 2 ] These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. [ 3 ]
The portion of the body closest to the prey is the portion the flatworm utilizes to grip the prey and ingest into its midventral mouth. [1] If the flatworm has been starved, it will lunge at the prey, grip onto it, and quickly ingest it. [1] However, if the flatworm is fed daily, it attacks normally and ingests at a slower rate. [1]
