Description
Note: the watermark will not appear on purchased prints. Cardisoma guanhumi, also known as the blue land crab, is a species of land crab found in tropical and subtopical estuaries and other maritime areas of land along the Atlantic coast of the Americas, in the United States along the Gulf of Mexico, from Brazil and Colombia, through the Caribbean, to the Bahamas, and as far north as Vero Beach, Florida. Cardisoma guanhumi is omnivorous, collecting and eating leaves and fruits close to its burrow whilst also eating insects and carrion. Like many crabs, this species is cannibalistic. They move in the shade during the day and will eschew moving in prolonged direct sunlight to feed at night instead. Cardisoma guanhumi finds its food using light and sound detectors. Experiments show that crabs can be drawn out of their burrows to investigate the sound of falling fruit, once out they initiate a search for food. Predatory behavior is released in these crabs by detection of small moving objects. Crabs in the genus Cardisoma are able to detect small vibrations on the ground within the range of 10�1500 Hz and 70 dB. Visual acuity increases with body size due to an increase in both the number and diameter of ommatidia.
I graduated from the Kemerovo State University of Culture and the Arts in Russia with a Specialist Degree in Theater Arts and Theatrical Education. I'm a self taught photographer and artist. Videography, Photography, and art is not just my profession and passion, but I would say it is also some kind of meditation and compilation process for me that helps to abstract my mind, and I'm glad to share my visions with you. Thank you very much for your interest. Olga Hamilton
