Arestorides argus, commonly called the eyed cowrie, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.[1]

Subspecies[edit]

Two subspecies are recognized :[1]

Description[edit]

This is a large cowry species, with specimens averaging 80mm and measuring up to 115mm.[1] The shape of the shell is approximately cylindrical. The ground color is light to medium tan. Overlying the ground color of the dorsum are many rings of a medium brown color and varying sizes. The rings are likened to eye spots, thus the common name eyed cowry and the specific epithet argus (after Argus Panoptes, the many-eyed Greek giant). Some individuals have numerous small rings, others have fewer, larger rings; the number and size of rings especially varies between subspecies. The aperture is relatively straight, has well-developed teeth, and is flanked by two dark-brown blotches on each side (the blotches on the outer lip are sometimes small and indistinct).
