Natica arachnoidea, common name the spider moon snail, is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails.[1]
Description
The size of an adult shell varies between 13 mm and 26 mm. The shell is predominantly yellow-orange, patterned with irregular reddish-brown reticulate maculations across its whorls, and the protoconch is reddish-brown in color.[2] As in other members of the genus Natica, the shell has a calcareous operculum and a circular to ovate umbilicus partially covered by fused parietal and umbilical calluses.[2]
Feeding and habitat
As a member of the family Naticidae, Natica arachnoidea is a predator targeting other mollusks, particularly bivalves.[3] Naticid gastropods detect buried prey through the sediment and use their extensible foot to envelop the prey item, after which they may bore circular holes through the prey shell using the radula in combination with chemical secretions.[3] Members of the family are most commonly associated with sandy substrates where burrowing prey are abundant.[2]
Distribution
This species is distributed across the Indo-Pacific, from the western Indian Ocean - including the Mascarene Basin and Mozambique - through the Andaman Islands and Southeast Asia, and into the Western Pacific as far as Fiji and the Marshall Islands, as well as Australia.[2] It does not extend further east in the Pacific Ocean.[2]
