Phylum: Mollusca, Class: Gastropoda, Order: Littorinimorpha, Family: Cypraeidae, Genus: Erronea, Species: Erronea errones · Cypraeidae (Cowrie family) · Gastropod; smooth, oval-shaped univalve shell with a hidden spire.
Species
Erronea errones
Shell Type
Gastropod; smooth, oval-shaped univalve shell with a hidden spire.
Family
Cypraeidae (Cowrie family)
Size
Approximately 25-30mm (1 inch). Typical adult size ranges from 18mm to 45mm.
Color & Pattern
Pale greenish-yellow to cream base color overlayed with mottled olive-brown bands. Features a distinctive scattering of small white spots on the lower sides and a characteristic large dark brown blotch on the center of the dorsum (partially obscured by wear in this specimen). The base and teeth are typically white/cream.
Rarity
Very Common. This is one of the most prolific and widely distributed cowrie species in its range.
Habitat
Intertidal and shallow subtidal zones; often found under rocks, coral slabs, and in crevice environments in muddy or sandy areas near reefs.
Geographic Range
Indo-West Pacific region, ranging from the East African coast to Australia and north to Japan.
Description
A smooth, egg-shaped gastropod with high natural gloss. The shell is characterized by its sub-cylindrical shape and a narrow, toothed aperture that runs the length of the underside. The dorsal surface shows a pattern of diffused brownish banding and spotting, while the margins are rounded rather than calloused.
Key Features
Smooth, tooth-lined aperture; lack of a distinct spire in adults; rounded 'shoulders'; and the presence of a central dorsal blotch (though this can be faded in beach-worn specimens).
Collector Value
Low. Because it is common and this specimen is beach-worn, its value is primarily educational or sentimental, typically ranging from $0.50 to $2.00 USD.
Condition Notes
Fair to Good. The shell shows visible beach wear with some loss of the original high-gloss porcelain finish (dulling) and fading of the dorsal blotches. There is some minor calcification or erosion on the anterior end.
Interesting Facts
The living animal has a mantle that can completely cover the shell, protecting it from abrasions and keeping it shiny. Historically, cowries were used as currency in many parts of the world, though this specific species was less common for trade than the Money Cowrie (Monetaria moneta).
Ecological Role
Herbivorous scavenger. They primarily graze on algae and detritus found on the substrate, playing a role in keeping reef surfaces clean. They are prey for octopuses and certain predatory snails.
Similar Species
Erronea caurica (typically more elongated with darker spots) and Erronea ovum (larger and more bulbous). It is distinguished from Monetaria by its larger size and lack of a yellow ring or knobby margins.
Beach Finding Tips
Look in tide pools at extremely low tide, especially under loose coral rubble or rocks. They are often found in silty areas where other cowries might not thrive.
