Austruca annulipes was formerly in the genus Uca, but in 2016 it became a member of the genus Leptuca, a former subgenus of Uca.[2][3][1]
They are relatively small crabs, and can be seen feeding in the evening at low tide. The males and females differ in size and appearance: the larger males are endowed with a brightly colored front claw. Compared to the females (and even the smaller male Uca annulipes crabs), the male Austruca annulipes crabs spend the most time excavating their burrows.[4] House crows are known to prey upon these crabs, which are quick to hide in their burrows at the slightest hint of danger.
