Nerite Snail
About the Nerite Snail in Singapore
Last updated 31 May 2026
The Nerite Snail (Nerita sp.) have a large, muscular foot that gives them a strong grip on hard surfaces. Adhesion is further enhanced by a mucus that they secrete. These mechanisms are important as they help Nerite Snails cling to rocks or vertical seawalls and avoid being swept away by crashing waves.
Identifying features
Check out some of the identifying features of Nerite Snails below.
Nerite Snails have thick hemispherical shells that come in a diverse range of colours and patterns. However, those on our shores are mostly black or brown. The spiralling ribs on a Nerite Snail’s shell are narrow, fine, and regularly spaced.
Habitat and ecology
Neritle Snails are abundant on seawalls and other hard substrate (such as rocks) along our shores. They are also voracious eaters that keep algae growth in check.
Did you know?
Nerite Snails have been heavily studied as an indicator of habitat health. Because of how much they eat, toxic chemicals (if present) may accumulate to observable levels in the snails, signalling their potential presence in our coastal ecosystems.
