sessile

sessile In zoology, describing an animal that remains fixed in one place. Sedentary animals, such as barnacles, limpets and mussels, are usually permanently attached to a surface. The term sessile is also used to describe the eyes of crustaceans that lack stalks and sit directly on the animal's head. In botany, sessile describes any structure that has no stalk (in cases where one might be expected) and grows directly from a stem.
