Phylum: Mollusca, Class: Gastropoda, Order: Littorinimorpha, Family: Cypraeidae, Genus: Cypraea, Species: Cypraea tigris · Cypraeidae (Cowrie family) · Gastropod, whole shell, ovate and dome-shaped
Species
Cypraea tigris
Shell Type
Gastropod, whole shell, ovate and dome-shaped
Family
Cypraeidae (Cowrie family)
Size
Approximately 2.5 to 3 inches, which is on the smaller to medium side for this species. Adults typically range from 2.5 to over 5 inches.
Color & Pattern
Glossy porcelain-like finish with a white to cream base heavily overlaid with dark brown to black spots and blotches, resembling feline markings. The base is white with a warm tone, and a distinct darker dorsal line is sometimes visible.
Rarity
Common, frequently found in reef environments and widely available in shell markets, though pristine live-collected specimens are less casually encountered on beaches.
Habitat
Found in shallow tropical waters, typically coral reefs, intertidal zones, and under coral heads or rocks down to about 30 meters depth.
Geographic Range
Indo-Pacific region, spanning from the east coast of Africa, across the Indian Ocean, through Indonesia and Southeast Asia, to Polynesia and the Central Pacific.
Description
A classic, heavy, and robust cowrie with a smooth, highly polished exterior. The shell features a distinctive rounded, dome-like dorsal surface curving smoothly down to a flat or slightly convex base. The aperture is narrow, long, and lined with prominent teeth on both the outer and inner lips.
Key Features
Smooth, glossy porcelain texture, ovate inflated shape, narrow toothed aperture, and characteristic dark brown or black spots scattered over a lighter cream background.
Collector Value
Moderately high in terms of traditional appeal, but low monetary value due to commonness. Standard specimens are inexpensive, while exceptionally large or aberrant pattern variants command higher prices.
Condition Notes
Appears to be a whole shell in generally good condition with natural glossy luster retained, though minor wear on the margins cannot be ruled out. Grade: Fine.
Interesting Facts
Cowries were historically used as a form of currency across parts of Africa, Asia, and Oceania. The living animal extends a mottled mantle that covers the shell, which prevents algae growth and keeps the surface polished.
Ecological Role
Acts as a nocturnal grazer feeding primarily on algae, sponges, and detritus on coral reefs. It serves as prey for large fish, octopuses, and specialized predatory snails.

Beach Finding Tips
Look in tropical intertidal zones, under large flat rocks, or within crevices of coral reefs during extremely low tides using snorkeling gear.
