Atlantic marsh fiddler crab (Minuca pugnax)
What to Look For:

Males have a patch of royal blue on the carapace, females do not. Males are also larger (15-23 mm) than females (13-18 mm). Both have narrow eyestalks and dark bands on their walking legs. Males have one greatly enlarged claw that is often yellow.
Where to Find It:
As you may guess by its name, the Atlantic marsh fiddler crab can be found in - you guessed it - Atlantic marshes. Check out Huntington Beach State Park or the marshes of Winyah Bay for this species!
Why It Is a Spotlight Species:
The Atlantic marsh fiddler crab is the most common fiddler crab along our coasts. They are impacted by climate change as their range creeps northward with warming waters.
