The first map shows the approximate density of species richness (click on map for larger view). The second map shows approximate point locations where fiddler crabs have been recorded in the scientific record. Purple fiddler crabs 
indicate locations where fiddler crabs are found; blue fiddler crabs surrounded by a dashed circle 
indicate the same but for larger, general regions; and red circles with an x 
indicate false or mistaken records. See the location index for a full list of all point locations.
Specific ranges for a species or name can be found on its associated pages. The list below sorts the species by major zoogeographic realm.
