Uca

Crane (1975)

Uca (Crane 1975) image
This drawing is from Crane (1975), although it appears to be a better redrawing of a figure from her 1966 paper. It is a semidiagrammatic figure of a vertical display position in fiddler crabs and not meant to represent a specific species, although it appears to be somewhat based on Uca maracoani.
