Caption

Laevapex fuscus, ventral view. The tan mass is the digestive gland. Although the ancylids are pulmonates and have a lung, they also have a pseudobranch (false gill, which is a secondary outgrowth of skin, not a true molluscan ctenidium) to aid in respiration. The triangular, lobulated pseudobranch is clearly evident in this view.
