Caecum Micro Sea Snail Shell

Here is a magnified image of a Caecum sp. sea gastropod shell. It was found in 2014 during a diving trip to Key West Florida, USA. The specimen was about 2 km off shore in about 5 meters under the water. I do not think this is a fossil. Viewed under microscope with a 3 mm field of view.

Thanks to Kenny for the specimen and Herb for letting me use his microscope.
