Morphology

genus + Uca

The phrase is directly compositional: 'genus' names a biological rank and 'Uca' is the taxon name, so 'genus Uca' straightforwardly means the genus called Uca. This follows common cross-linguistic scientific naming patterns, so a B1 learner who knows both constituents would understand the meaning.

Etymology

Genus Uca likely comes from an old local word for the small crabs called 'fiddler crabs'. Male fiddler crabs hold one very large claw and wave it like someone playing a fiddle, so the name Uca became the group name for crabs with that 'one very large claw'.
