Phylum: Mollusca, Class: Gastropoda, Order: Littorinimorpha, Family: Cypraeidae, Genus: Cypraea, Species: Cypraea tigris · Cypraeidae (Cowrie family) · Gastropod (snail/univalve), whole shell, ovate or oval shape
Species
Cypraea tigris
Shell Type
Gastropod (snail/univalve), whole shell, ovate or oval shape
Family
Cypraeidae (Cowrie family)
Size
Approximately 2 to 3 inches visible in this mixed display, which is on the smaller-to-average side for this species; adult tiger cowries typically range from 2.5 to 5.5 inches (60 to 140 mm).
Color & Pattern
Glossy cream-to-white base color densely covered with dark brown to black spots and blotches resembling the pattern of a tiger or leopard, accompanied by a distinct dark marginal line or band along the base; colors appear natural and highly polished with a porcelain-like vitreous luster.
Rarity
Common, widely distributed across the Indo-Pacific and frequently collected or traded, though pristine live-taken specimens vary in market availability.
Habitat
Found in tropical marine waters, typically in shallow subtidal zones, coral reefs, and intertidal areas beneath coral rubble, rocks, and in crevices down to depths of about 30 meters.
Geographic Range
Indo-Pacific region, spanning from the east coast of Africa, through the Indian Ocean, and across to Polynesia and the central Pacific.
Description
A classic porcelain-like cowrie shell with a heavily inflated, smooth, and highly polished dorsal surface. The pattern consists of striking dark spots over a lighter background. The ventral side features a flattened base with long, narrow, toothed apertures on both sides.
Key Features
Involute spire hidden in adults, heavily polished glossy finish, rounded and inflated margins, and a distinct patterned dorsal surface with dark brownish spots.
Collector Value
Moderately high general appeal as a classic decorative shell, though very common in shell shops. Exceptionally large specimens or those with unusual color aberrations command higher prices among advanced collectors.
Condition Notes
Good to Fine condition, displaying a glossy exterior with clear patterning, showing minimal wear and no major structural fractures.
Interesting Facts
The mantle of the living snail can extend completely over the shell to protect it from fouling organisms and keep it polished. Cowries were historically used as a form of currency across parts of Africa and Asia.
Ecological Role
Acts as a benthic grazer feeding primarily on algae and sponges, contributing to the health of coral reef ecosystems by controlling algal growth.
Similar Species
Arabian Cowrie (Luria arabica) or Mauritian Cowrie (Cypraea mauritiana), which can be distinguished by their different geometric line patterns or darker, more angular dorsal markings rather than distinct spots.
Beach Finding Tips
Search under large flat rocks, coral slabs, and deep crevices during extremely low spring tides in tropical Indo-Pacific reefs, or look among drift lines after major storms.
