Phylum: Mollusca, Class: Gastropoda, Order: Littorinimorpha, Family: Cypraeidae, Genus: Cypraea, Species: Cypraea tigris · Cypraeidae (Cowrie family) · Gastropod (snail/univalve), whole shell, ovate/globular shape
Species
Cypraea tigris
Shell Type
Gastropod (snail/univalve), whole shell, ovate/globular shape
Family
Cypraeidae (Cowrie family)
Size
Approximately 2.5 inches, which is on the smaller side for this species. Adults typically range from 3 to 5 inches, with exceptionally large specimens reaching over 6 inches.
Color & Pattern
The dorsum features a creamy white or light yellowish base overlaid with dark brown to black spots and blotches resembling tiger stripes, characteristic of the species. A distinct pale dorsal line runs lengthwise. The colors appear natural and glossy, though slightly weathered.
Rarity
Common, frequently found in its natural range and widely available in shell shops worldwide.
Habitat
Found in shallow tropical waters, typically from the intertidal zone down to about 30 meters. It strongly prefers coral reefs, hiding under coral heads, in crevices, and among rubble during the day.
Geographic Range
Indo-Pacific region, spanning from the east coast of Africa across the Indian Ocean to Southeast Asia, Indonesia, Australia, and Polynesia.
Description
A classic, highly polished cowrie shell with a smooth, porcelain-like exterior and a heavy, robust, dome-shaped form. The base is flattened with teeth lining both sides of the narrow, long aperture.
Key Features
Distinguished by its heavy, inflated oval shape, smooth glossy finish, characteristic dark brown spots on a light background, and toothed margins along the underside aperture.
Collector Value
Low to moderate commercial value. While iconic and beloved by beginner and intermediate shell collectors, they are very common. Pristine, exceptionally large specimens command higher prices, but standard specimens are inexpensive.
Condition Notes
Good condition. The shell is intact with nice glossiness, though minor surface wear is visible around the margins. Grade: Good to Fine.
Interesting Facts
Live cowries possess a mantle that covers the shell, protecting it from fouling organisms and depositing the shiny outer layer of enamel. Historically, some cowrie species were used as a form of currency.
Ecological Role
Active nocturnal grazers that feed primarily on algae and sponges growing on coral reefs, helping to maintain reef health. They are preyed upon by specialized carnivorous gastropods, octopuses, and fish.
Similar Species
Arabian Cowrie (Cypraea arabica) and Panther Cowrie (Cypraea pantherina). Panther cowries have smaller, more numerous spots, while Arabian cowries have a distinct tented pattern.
Beach Finding Tips
Look along tropical reef flats at extremely low tide, turning over loose coral rubble and slabs, though live collection is discouraged in many protected marine parks. Beach-worn shells are sometimes cast up on reef-adjacent beaches.
