Description The Podophthalmus vigil is easily to identify by its enormously long eye stalks, a feature that cannot be seen in any other crab species. It can see longer distances and possibly allow the crab to keep the eyes in clearer water above the turbid silt. Light green carapace on dorsal view and underneath the chelipeds maroon or violets in adults. Carapace distinctly broader than long: anterior margin much broader than posterior margin. There are only two anterolateral teeth at the carapace.
