The wood mouse "Apodemus sylvaticus" possesses spermatozoa with falciform morphology. A common misconception is that the falciform ligament separates the two lobes. The falciform ligament contains the round ligament of liver. The falciform ligament divides the liver into a left and right lobe. The falciform ligament can become canalised if an individual is suffering from portal hypertension. The teeth of the toxoglossan radula are falciform and angulated (formula 1-0-1). The falciform ligament droops down from the hilum of the liver.
