Naticidae Guilding, 1834

Common Name: Moon snails


Key morphological features: The Naticidae are mostly medium sized gastropods with delicate to solid to globose shells. The shells are umbilicate (have a hole at the base of the shell whorls). The spire is low and the body whorl is large. Naticid shells have a smooth exterior, but some species have weak sculptural patterns.


Paleoecology: The Naticidae are predatory marine gastropods that prey primarily on other mollusks by enveloping the prey in their muscular foot and drilling a beveled, circular hole through the shell through which they consume the prey’s flesh. They can be found at temperate to tropical latitudes.
