[Note Guidelines] Photographer's Note
Ghost crabs, also called sand crabs, are crabs of the genus Ocypode, common shore crabs in many countries. These are frequently seen scurrying along beaches between sunset and dawn.

These crabs are called ghosts because of their ability to disappear from sight almost instantly, scuttling at speeds up to 10 miles per hour, while making sharp directional changes. These creatures have two black eyes, with sharp 360° vision which they use to see flying insects and catch them in mid air. The ghost crab, however, cannot see directly up, so it must burrow into the ground to prevent birds from catching it.

The ghost crab tunnels down four feet into the ground at a 45° angle, creating 1-2 inch wide holes, which speckle the beach. At dusk, these crabs will sprint to the ocean in order to obtain oxygen from the water which washes over their gills, and in June, females will release their eggs into the ocean. Ghost crabs hibernate during the winter, holding their breath for six weeks, by storing oxygen in sacs near the gills.

Characteristics of the genus include one claw being larger than the other, but not as profoundly as for the male fiddler crab.

This was an enormous effort to shoot this ghost crab. They are so fast and are so eloquently camouflaged that it is difficult to spot them leave aside focus on them in the sand. It was pure luck that 5/6 shots were OK out of about 100. I wished my POV was a little lower but as the sand was wet and I was not prepared for this adventure I had to crouch and remain still and alert at the same time. Oh......it was painful. I hope this is a satisfactory shot. Still I have got to try some other POVs someother time. Shot taken hand held, early windy morning. Puri Sea Beach.

Hello Sumon,
Perfect body color to blend in the sand. No wonder this is a difficult shot. You did well with this picture. The image is sharp and well exposed. Also beautiful morning sun that casted on this Ghost crab.

Hi Sumon,
A very nice shot on this Ghoast Crab. His colors blend with the sand perfectly. Nice sharp detail. Sounds like you had to work hard to get this shot. Well done, nd well worth the effort.

Hello Sumon.
Great colour and exposure here.
This is amazing looking sand.
The huge brown crystalline grains look like raw sugar, or even demarara sugar!
Fantastic shot.
Cheers,
Steve

Hi Sumon,

An amazing capture of this ghost crab. He is so well camouflaged yet you show him and his hole clearly and sharply. The colors are wonderful. You show us the textures of the wet sand so well. A wonderful photo.

Your note gives a very good idea about the habits, activities and life-style of this Ghost Crab, Sumon. I have a very limited experience of wild life by the sea, so it has been a great help in understanding this creature and admiring its picture you have taken on the beaches of Puri which I have seen only once in the past many years ago.
I notice that the colour of the crab and the sand is almost similar.
You have captured the fellow in the middle of digging action. Was is going in coming out?
Thanks for sharing this interesting image and best regards.

Hello Sumon,

Hello Sumon

I love the eyes ,wonderful detail and sharp focus.The composition is very good.The crab is so similar to the sand ,but the detail is still sharp and the crab colours are still quite evident.Well done.TFS

Rob

I have seen these...they are wonderful are they not...and you cannot go wrong taking a pic of them unless they get in soft sand like a clam...but clams are faster..and your click is tied...so keep it up..Very sharp..nice earth tones...yeah I guess I am an old philosopher hippie....did you know that science GREW OUT of philosophy? My mother taught me that...

Hi Sumon,
Fabulous shot! What camouflage! The details are very crisp and the colours are awesome. TFS.
Cheers, Uma

Hi Sumon,
I really like that the sand and the detail which the sand creates in the photo is in focus. The crab is almost hidden. Good sharp and interesting shot.
regards
Matt.

Wow - that is a great macro. No wonder that it is called Ghost Crab - it blends perfectly with the sand. So your pain paid off. Great detail and interesting info! Cheers, Klaus

Vry well done !
