The Red-jointed Fiddler Crab was showing aggression in protecting his territory found in Emerson Point Preserve on Snead Island Palmetto Manatee County Florida U.S.A.
I've been planning to catch one of these guys and take his picture, but hadn't yet had the spirit to do so. Last evening, late, when walking our Golden Retriever, he was stopped and clearly observing something in the grass and with great caution. Sure enough, this male fiddler crab was in our front yard. We live along the wetlands and sometimes various creatures, crabs, turtles, etc get a little disoriented and wander in the wrong direction. And so I protected this little fellow overnight and early this morning, set about capturing his portrait before his release. It seems that getting him to hold still was the greatest challenge, but patience prevailed and he held fast for a good series. This is a stack of 13 images using the Helicon FB tube to automate the focus stacking and Helicon Focus software to process the stack. After posing for this portrait, he was harmlessly released back into the wetlands. The Atlantic Marsh Fiddler Crab (Uca Pugnax) is a small crab that eats algae and decaying material in the mud. They burrow holes in the mud and help aerate the wetlands, which is most beneficial for its health. The male of the species has a very large claw and this is one of the largest I've seen. The biggest claw and the one that gets 'waved' fastest gets the female in their world, as this is the mechanism by which they attract members of the opposite sex. If you zoom in, you'll find a fascinating array of details, all of which serve some purpose (whiskers, sideburns, hairy legs, etc). And by no means last in unusual features, you will see the eyes on stalks. These stalks fold in to protect them from damage when burrowing into tight places, but otherwise they are an incredibly sensitive array of sensors for detecting predators. These crabs spend their low-tide life on flat stretches of mud, where they quite vulnerable to overhead predation from various birds that consider these crabs a delicacy. Accordingly their eyes have evolved to exist on stalks that afford 360 degree visibility and elevated so that they can see well above the horizon line from which danger comes. It's how they survive! And you wonder where they came up with some of the sci-fi creatures? Here at home!

Good morning. Sorry for my absence here the past few days, but things have been a little hectic lately. Hopefully over the next two days I'll be able to catch up on things and visit with everyone.
For today I'd thought I'd post a series featuring Fiddler Crabs, which until recently I never knew were kept by aquarist along with fish. I know, strange thing to be posting after being gone for a few days. Especially when considering the last photo I posted was of my footsies. No connection though :-)
As for these photos, all the crabs photographed were underwater in a tank along with Angelfish. The above male couldn't have posed more perfectly and of all the crabs had the largest claw in proportion to body size, although the crab itself was quite small. Maybe 3/4 of inch (2 cm) across the body excluding the legs and large claw. And the above photo is the only one in the set taken with my new camera (Pentax K20D) while the photos in the comment section were taken with a K10D during an earlier visit. At ISO800 in poor light, shooting through glass and water, I'm pretty impressed with how it turned out.
I hope you enjoy this series and find the text in the comment section on this interesting little crustacean informative.
Thank you for stopping by...and I hope you have a truly pleasant day.

The Fiddler Crabs retreat to their muddy holes quite readily, but occasionally there's one that ready to stand its ground.
I was happy to have gotten a picture of this fiddler crab after being bit by many black flies that were hanging around the marsh! I got a picture of him and then left as fast as I could :-)!
A male West African fiddler crab trying to attract the attention of the ladies with his impressive claw. The text books say that these crabs should be in hibernation by November. Hundreds on the ground disagree.
Photographed in the Olhão Salinas, but they were present all along the Ria Formosa.
Fiddler Crab at Robinson Preserve, Bradenton (FL). There were thousands of them today, but they move really fast and you have to wait for the right moment to get a good shot.

Hoping for more skimmers, I ended up with more Fiddler Crabs. They seemed pretty aggressive, between eating and dueling. The guy on the left appeared to go after the guy on the right. At one point, righty backed into his hole till there was only his big claw sticking out. Even more, as he withdrew deeper, it looked like lefty was trying to pull righty's claw off. Or so it seemed. Fun stuff.
Video could have been a good idea, and it did cross my mind, but you can see the hunking glass I had today. I couldn't even see these little guys with my naked eye because of the far-away close-focus distance of the glass.
At low tide dozens of fiddler crabs emerged from their sandy burrows and were scurrying everywhere on the beach. These tiny crustaceans live in mudflats, beaches and marshes throughout the Chesapeake Bay region. Males have one enlarges claw while female claws are of equal size.

These are fiddler crabs. They're about the size of a bumble bee and we seem them scurrying along in the mud by our dock at low tide. They have one small claw and one large yellow one.
Our lodge was on a tidal tributary of the River Gambia which provided the opportunity to see some of the interesting smaller creatures of the mangrove tidal zone.
The male fiddler crabs have a huge right claw (that looks like a fiddle and so the animal gets that name), which they use to display and attract females. Except for this purpose, this claw is believed to have no other use.
However, in this picture, where the fiddler crab makes its display to shoo off opponents, this frame appears as though it is using the arm as a sun-shade, though it is obviously not using it so!
Fiddler crabs ((Uca tangeri) were seen all over the wet areas near the salt processing ponds. They come out to feed during the daylight hours. These fellows dart back and forth into their holes, when scared. These were seen along the Algarve coastline, near the heart of Ria Formosa Nature Reserve.

(2019) Fiddler Crab with Red Pincer
This is a digitally colored illustration of a stylized fiddler crab, showing off it's over-sized major pincer.
Painted this today as an exercise, and the original sketch was drawn on April 30th, 1995.

Thick-legged Fiddler Crab (Paraleptuca crassipes), Fiji
Paraleptuca crassipes or the thick-legged fiddler crab is a species of fiddler crab that lives in intertidal habitats distributed across the western Pacific Ocean.
Paraleptuca crassipes was formerly a member of the genus Uca, but in 2016 it was placed in the genus Paraleptuca, a former subgenus of Uca.

These male fiddler crabs are checking for danger around their feeding spot in a synergistic manner.
By feeding with their backs together, then can check for danger in a 360-degree angle and with the quick movement, can warn off each other.
They do compete for food, terrain and mates. However, they also have such altruistic safety mechanisms to extend their lives and get more chances to contribute to future generations.
Only male fiddler crabs have fiddle like enlarged pincers. Since females have two similar sized pincers, they can pick food with both pincers and eat quicker than males.
However, males require this additional load that prevents them from eating quickly. They would have to eat with only their one pincer, while the enlarged one is just for display, which will get them a chance to mate. In fiddler crab's world, the Romeo with largest of pincers would get his Juliet!
Feeling crabby? These little guy can sum it up for many of us, at the end of a long, hard day. Since tomorrow is Friday, I hope everyone is in a better mood than my little Fiddler Crab.
Fiddler Crabs are characterized by a marked difference in the size of the two claws.

A male West-African fiddler crab (Afruca tangeri) trying to make an impression in the muddy floor of a Tavira salina.
These crabs are noticeably increasing in numbers in the salinas and along the shores of the Ria Formosa. Their burrowing activities - 5cm holes up to 1m long - are undermining the earth banks between salinas causing them to collapse.
