Kenkia glandulosa

Kenkia glandulosa, commonly known as the pink planarian, is a flatworm in the family Kenkiidae. It is found only in the Devil's [Icebox (cave)|Devil's Icebox cave] in Rock [Bridge Memorial State Park], Boone County, Missouri, United States. The rarity of this species was once cited as a reason to oppose the construction of a shopping mall in the area.
The species is an eyeless and depigmented flatworm that inhabits the undersides of rocks. It is currently a species of conservation concern in the state of Missouri.
