A sinuous channel on the surface of Venus; pl.canali. Canali are found on low-lying plains and have near-constant cross-sections and widths. They are typically a few hundred kilometres long and a few kilometres wide, Baltis Vallis being the longest at 6800 km. The smoothness and great length of canali point to the flow of very fluid lava as their cause.
