Phylum: Mollusca, Class: Gastropoda, Order: Littorinimorpha, Family: Cypraeidae, Genus: Cypraea, Species: Cypraea tigris · Cypraeidae (Cowrie family) · Gastropod (snail/univalve), whole shell, ovate shape with an engraved souvenir modification
Species
Cypraea tigris (or similar large cowrie species)
Shell Type
Gastropod (snail/univalve), whole shell, ovate shape with an engraved souvenir modification
Family
Cypraeidae (Cowrie family)
Size
Approximately 2.5 to 3 inches in length, which is a medium-sized specimen for this species whose adults typically range from 2.5 to 5 inches.
Color & Pattern
The natural dorsal pattern has been largely obscured or altered by an artificial dark brown or reddish-brown top-coat or acid-etching technique to reveal a white, engraved commemorative design featuring the text LOS ANGELES 1984 CALIFORNIA and figures of athletes.
Rarity
Common in its natural state, but this specific vintage souvenir-carved or acid-etched variant is an uncommon novelty collectible.
Habitat
Typically found in tropical marine waters, living in shallow subtidal zones, coral reefs, under coral blocks, and in crevices from the intertidal zone down to about 30 meters.
Geographic Range
Indo-Pacific region from the eastern coast of Africa through the Indian Ocean to the central Pacific, though this specific modified specimen is a tourist souvenir from Los Angeles, California, dating to the 1984 Summer Olympics.
Description
An ovate, highly polished marine gastropod shell modified as a vintage Olympic souvenir. The dorsal surface features a deep reddish-brown application or etching revealing a cameo-like white design depicting two runners holding a torch, flanked by the text 'LOS ANGELES' above, 'CALIFORNIA' below, and '1984' centered at the base. The underlying cowrie shell exhibits a smooth, glossy porcelain-like finish typical of cowries.
Key Features
Ovate, rounded cowrie shape, smooth and glossy exterior texture, narrow and toothed aperture (hidden in the view, but characteristic of the family), and the prominent custom engraved or etched 1984 Los Angeles Olympic motif.
Collector Value
Low to moderate commercial value primarily driven by novelty, vintage memorabilia, and Olympic collectors rather than conchological value, as the natural shell has been altered.
Condition Notes
Good vintage condition. The shell structure is intact with a glossy finish, but it has been artificially altered (etched, dyed, or engraved) for commemorative purposes, removing the natural dorsal pattern.
Interesting Facts
Cowries were historically used as a form of currency in various parts of Africa and Asia. This particular shell serves as a piece of Olympic memorabilia, commemorating the 1984 Summer Olympics held in Los Angeles, California.
Ecological Role
Living cowries are marine grazers that feed on algae, sponges, and detritus, helping to maintain reef health. They are preyed upon by specialized gastropods, fish, and crustaceans.
Similar Species
Other large cowries such as the Leopard Cowrie (Cypraea pantherina) or Mauritian Cowrie (Mauritia mauritiana), which are distinguished by their natural spot patterns before any souvenir modifications are applied.
Beach Finding Tips
Natural cowries are found by snorkeling or scuba diving around coral reefs, turning over loose rocks and slabs at low tide in tropical Indo-Pacific waters. Souvenir cowries like this are typically found in antique stores, flea markets, or souvenir shops.
