Zebra Nerite, also known as Zebra Neritina
Phylum: Mollusca, Class: Gastropoda, Order: Neritida, Family: Neritidae, Genus: Vittina, Species: Vittina turrita · Neritidae (Nerite family) · Gastropod (freshwater/brackish snail), whole shell, globular spiral shape
Species
Vittina turrita (formerly Neritina natalensis or Vittina natalensis in the trade)
Shell Type
Gastropod (freshwater/brackish snail), whole shell, globular spiral shape
Family
Neritidae (Nerite family)
Size
Approximately 0.5 to 0.75 inches, which is average for this species. Adults typically range from 0.5 to 1.0 inch.
Color & Pattern
Striking high-contrast pattern featuring dark black or deep brown zigzag, wavy, or zebra-like stripes over a lighter background of yellowish, greenish, or golden-brown. Colors are natural and glossy.
Rarity
Common in specialized pet and aquarium trade, but locally uncommon depending on specific wild collection regions.
Habitat
Freshwater and brackish habitats including tropical streams, rivers, estuaries, and mangrove swamps, often clinging to rocks, submerged wood, and aquatic plants.
Geographic Range
Native to East Africa, particularly regions including Kenya, Mozambique, Tanzania, and South Africa, but widely distributed in the Indo-Pacific and popular globally in the aquarium trade.
Description
A charming and compact freshwater nerite featuring a smooth, glossy, globular shell adorned with bold, zigzag zebra stripes. The aperture is semicircular with a flattened operculum and a solid, durable structure designed to withstand strong river currents.
Key Features
Globular spiral shape with a low spire, smooth polished exterior, and distinctive high-contrast black zebra stripes over an olive or yellowish base, combined with a freshwater/brackish habitat preference.
Collector Value
Low to moderate commercial value as a decorative shell or live aquarium specimen. Typically sold in pet stores rather than specialized high-end conchology shops.
Condition Notes
Specimens appear intact, glossy, and in Fine to Gem condition with well-preserved natural color patterns and minimal erosion.
Interesting Facts
Zebra nerites are famous in the freshwater aquarium hobby as tireless algae eaters. Unlike many aquarium snails, they cannot successfully reproduce in fresh water because their larvae require brackish or marine conditions to survive.
Ecological Role
Acts as an important grazer in freshwater and estuarine ecosystems, feeding on microalgae and biofilm to help control algal growth on rocks and submerged vegetation.
Similar Species
Neritina pulligera and Neritina natalensis; can be distinguished by specific variations in stripe thickness, background coloration, and regional shell morphology.
Beach Finding Tips
Found by searching along muddy riverbanks, mangrove roots, and rocky substrate in tropical East African estuaries, though more commonly sourced through aquarium suppliers.
