(R.B. Hinds 1844) - Common name Centrifugal murex - Size range 35mm-94mm - Range: Sea of Cortez, West Mexico, Galapagos
Very rare dark coloring on this specimen. I've been selling these for 6 years and this specimen is one of the nicest and largest I've ever seen. Collected live by shrimping boats. Trawled from 80-150 meters depth, near and around the Wagner Basin in the northern Sea of Cortez. Very minor damage, which is astounding after being dragged along the bottom, then dumped on the deck of the shrimp boats. It's taken me years to get some very nice specimens.
These were still alive when presented to me. I removed the snail and minimally cleaned the shell of the extreme build up. They come covered in polyps and almost each one had a symbiotic sea anemone attached. I have photos of live specimens I can send if requested. Notice that there is still a little build up left because I did not want to overclean. Feel free to continue cleaning if desired. I did put a light coating of mineral oil on the shell to bring out the striations and any coloring. You can wash in simple soap and water to remove the oil.
See the size range from gastropods.com 94mm being the largest size. This one is very close. I am grading this at F++/GEM, I can see no discernable damage. You can compare this specimen and the ones on Ebay. My specimens are much larger and better quality, for better price.
