Blue Fiddler Crab
Species: Uca tetragonon
Only one out of 200, this is one of the most beautiful types of fiddler crabs I found in KK Wetland. Fiddler crabs may be tan, blue-green, turquoise, black, yellow, or orange in colour. When feeding, fiddlers may skip into the nearest available burrow to escape predation, or dig a quick temporary burrow.
