Bleeding Tooth Nerite
Phylum: Mollusca, Class: Gastropoda, Order: Cycloneritida, Family: Neritidae, Genus: Nerita, Species: Nerita peloronta · Neritidae (Nerite family) · Gastropod (univalve); globose/spiral shape
Species
Nerita peloronta (approx. 85% confidence due to bokeh/blur)
Shell Type
Gastropod (univalve); globose/spiral shape
Family
Neritidae (Nerite family)
Size
Approximately 15-20mm (0.6-0.8 inches). Normal adult range for this species is 10-50mm.
Color & Pattern
Base color appears creamy white to pale grey with hints of pinkish-red or orange markings typical of the species. The blur obscures the zigzag or mottled patterns usually present on the exterior.
Rarity
Common beach find in its native range, though large, well-pigmented specimens are more sought after.
Habitat
Intertidal zone on rocky shores; specifically likes more exposed rocks where it can cling to avoid wave action. Found in marine environments.
Geographic Range
Tropical Western Atlantic, including Florida, the Caribbean, and Bermuda.
Description
This is a thick, globose gastropod shell with a low spire. The shell is known for its heavy, semi-circular calcareous operculum and a parietal area often bearing red-orange 'blood' stains around white columellar teeth.
Key Features
Red stains and two prominent white teeth on the columellar deck (if viewed from the aperture side); heavy, porcelain-like texture; rounded whorls.
Collector Value
Minimal financial value ($0-$1) due to heavy erosion and commonality; value is primarily sentimental for personal collections.
Condition Notes
The specimen appears significantly beach-worn and sun-bleached. The apex seems eroded, and the fine surface detail is lost. Collectibility grade: Fair/Poor for collectors, but a nice personal souvenir.
Interesting Facts
The 'blood' around the teeth is actually a pigment used to deter predators. In some Caribbean cultures, they were historically gathered for food or used as decorative beads.
Ecological Role
Primary grazer; they scrape algae from rocks using a specialized radula, helping to manage algal growth on coastal rock faces.
Similar Species
Nerita fulgurans (Antillean Nerite) which lacks the red staining, and Nerita versicolor (Four-toothed Nerite) which has more teeth and lacks the 'bleeding' pigment.
Beach Finding Tips
Look in rocky tide pools or high on the splash zone of limestone rocks at low tide. They are often found huddled in crevices to maintain moisture during the day.
