Description
Liana was defined as land planarians with a broad and elongated body. The cutaneous musculature is strong dorsally and weak ventrally, where it is partially sunk into the mesenchyma. The sensory border has rare and minute sensory pits restricted to the anterior tip. The copulatory apparatus has a short and blunt penis papilla and the female canal enters the genital antrum ventrally.[1]

gollark: They probably have the quadratic, cubic and quartic formulae programmed into them.
