The term lacus (lake) refers to a number of small low-albedo plains on the Moon and Titan and also to one on Mars. Lacus features usually exhibit a well-pronounced and sharp boundary and have a size of 100–200 km in diameter. While on the Moon lacūs are associated with Mare features and caused by basaltic flood volcanism, lacūs on Titan refer to small dark areas possibly associated with liquid hydrocarbons.
