Abstract
The visual acuity of the fiddler-crab was measured by means of its response to a moving visual pattern and was found to vary with log intensity similar to man, the bee, and Drosophila. Monocular and binocular visual acuity is similar with a maximum of 0.0042. In the fiddler-crab as in Drosophila, the minimum visual angle corresponds to approximately twice the minimum angle between 2 adjacent receptors.This publication has 4 references indexed in Scilit:
