Bleeding Tooth Nerite (Fragment/Eroded Apex)
Phylum: Mollusca, Class: Gastropoda, Order: Cycloneritida, Family: Neritidae, Genus: Nerita, Species: peloronta · Neritidae (Nerite family) · Gastropod (snail/univalve); heavily eroded spiral fragment consisting of the apex and columellar area.
Species
Nerita peloronta
Shell Type
Gastropod (snail/univalve); heavily eroded spiral fragment consisting of the apex and columellar area.
Family
Neritidae (Nerite family)
Size
Approximately 5-8mm in its current state. Full-grown adults reach 1-2 inches (25-50mm). This is a tiny, water-worn juvenile or apex fragment.
Color & Pattern
Base color is off-white to cream. It shows faint yellowish-orange staining near the columellar area, characteristic of the 'bleeding' coloration this species is named for. The natural zigzag black/red patterns are worn away.
Rarity
Very Common. These are among the most abundant snails on rocky Caribbean shorelines, though finding intact, vibrantly colored specimens is preferred by collectors.
Habitat
High intertidal zone on wave-swept rocks. These snails live above the low-tide mark, often in the 'splash zone' where they are sprayed by crashing waves.
Geographic Range
Tropical Western Atlantic; common throughout the Caribbean, Florida Keys, Bermuda, and the Gulf of Mexico (including Cancun).
Description
An extremely water-worn fragment of a gastropod. The specimen retains the thick, calcified structure of the inner whorls and the flat columellar deck. Despite the erosion, the robust nature of the Neritidae family is evident in the density of the remaining shell material.
Key Features
The most diagnostic feature remains the remnant of the flat columellar area and the hint of orange/red staining. The heavy, globose spiral shape, even when eroded, is typical of the Nerita genus.
Collector Value
Minimal to none. Intact 'Gem' quality specimens with bright colors and sharp 'teeth' hold modest value (1-5 USD), but beach-worn fragments are generally considered beachcomber keepsakes rather than collector pieces.
Condition Notes
Poor/Beach-worn. The shell is missing the outer lip and most of the body whorl. It has been significantly tumbled by surf and sand, removing the delicate teeth and surface sculpture. Collectibility grade: Poor.
Interesting Facts
In live specimens, the 'blood' is actually a red-orange stain on the white teeth of the columella. Historically, nerites have been used as food in the West Indies and their thick shells make them very resistant to crushing by predators like crabs.
Ecological Role
Grazer. They play a vital role in controlling algal growth on coastal rocks. They are a food source for hermit crabs and various shorebirds.
Similar Species
Checkered Nerite (Nerita tessellata) which is smaller and lacks the orange stain, and the Four-toothed Nerite (Nerita versicolor) which has different spotting and tooth arrangement.
Beach Finding Tips
Look in the rocky crevices and 'ironshore' limestone formations along Cancun's coast. They are best found at low tide clinging to rocks just above the water line.
