The Anurognathus is a diminutive pterosaur, with a wingspan of only about 1.5 feet, making it one of the smallest flying reptiles of the Mesozoic era.

This pterosaur primarily feeds on insects, using its wide, frog-like mouth to catch and consume prey mid-flight, making it a highly effective aerial insectivore.

The Anurognathus is notable for its very short tail, which contrasts with the long tails of many other pterosaurs, contributing to its compact and agile flying abilities.

Evidence suggests that Anurognathus may have been nocturnal, relying on its large eyes to hunt insects during the night, similar to modern-day nightjars or bats.
