Cypraea pantherina
A tropical cowry with a slender, spotted shell, endemic to the Red Sea.
Cypraea pantherina, called the panther cowry, is a large tropical sea snail—a marine gastropod mollusk in the cowry family, Cypraeidae. Along with Cypraea tigris, it is one of just two species still placed in the genus Cypraea; all other former members have been moved to other genera within the family. Shells of this cowry have turned up in Rhine valley tombs dating to 6 BCE, and specimens of both this species and Cypraea tigris were found at Pompeii, where they may have served as ornaments.
The panther cowry closely resembles Cypraea tigris but has a more slender, lighter shell. Typical shells measure 57–65 mm in length, with a range from 37 mm to 118 mm. The shape is roughly elongate-pyriform and feels heavy for its size. The dorsum is smooth and shiny, usually whitish or pale brown, and densely dotted with dark brown circular spots. A faint, blurred reddish line runs lengthwise along the midline—the line where the two halves of the mantle meet in the living animal. Shell color varies widely, from melanic or chestnut red to albino. The lower margins are rounded; the ventral side is white or whitish, with many long, fine teeth lining the aperture. In live individuals, the mantle is thin and quite transparent, marked with many fine longitudinal lines and numerous long, white sensory papillae. The mantle’s lateral extensions can cover the entire shell, meeting at the dorsum’s midline, and can be withdrawn into the shell opening when the cowry feels threatened.
This species is endemic to the Red Sea (off Egypt and Sudan), the Gulf of Aqaba, the Dahlak Islands, and the Gulf of Aden. Its range does not overlap with that of Cypraea tigris. It has also become established in the Mediterranean, around Lampedusa Island and Malta, likely after entering through the Suez Canal. The panther cowry lives in clear water at depths of 3 to 40 meters, mainly on coral colonies or sandy sea floors, feeding on coral polyps, various invertebrates, algae, and dead organic matter.
Recognized subspecies and forms include Cypraea pantherina pantherina, the form albonitens, form catulus, form funebralis, form nigrovinosa, and the subspecies Cypraea pantherina rasnasraniensis.

Lore & Background
Shells of Cypraea pantherina have been found in tombs in the Rhine valley dated to 6 BCE. Additionally, shells of this species and the related Cypraea tigris have been unearthed at Pompeii, the ancient Roman city near Naples, Italy, where they may have been used as ornaments. The species looks very similar to Cypraea tigris, but its shell is more slender and lighter. The dorsum surface is smooth and shiny, usually whitish or pale brown, densely covered with dark brown circular spots, and a blurred longitudinal reddish line runs along the midline where the two halves of the mantle meet in life. Basic colors are very variable, ranging from melanic or chestnut red to albino. The ventral side is white or whitish, with several long and fine teeth along the aperture. In live animals the mantle is thin and quite transparent, with many longitudinal slight lines and numerous long and white sensorial papillae; the lateral extensions may cover the shell completely, meeting at the midline of the dorsum, and can be withdrawn into the shell opening when the cowry is threatened.
Reader's Guide
Cypraea pantherina is notable as one of only two species retained in the genus Cypraea, alongside Cypraea tigris, after all other species previously belonging to the genus were reassigned to other genera within the family Cypraeidae. Its shells have been recovered from archaeological contexts, including tombs in the Rhine valley from 6 BCE and at Pompeii, suggesting historical use as ornaments. The species is endemic to the Red Sea, Gulf of Aqaba, Dahlak Islands, and Gulf of Aden, and its range does not overlap with Cypraea tigris. It has also become established in the Mediterranean Sea, likely having entered through the Suez Canal. The panther cowry lives in clear water at depths of 3 to 40 meters, mainly on coral colonies or sandy sea floor, feeding on coral polyps, various invertebrates, algae, and dead organic matter. Several forms and one subspecies have been described, including Cypraea pantherina pantherina and Cypraea pantherina rasnasraniensis.
