Nerita

Family Neritidae


There are many species of this common and interesting shell along rocky shores, especially on man-made structures. The shell colour pattern is quite variable even within a species. They are algal and lichen feeders.

Their egg cases are white, disc-like, and attached onto the lower surfaces of rocks or wood. (Shell 2-3cm).

Family Neritidae


These small snails are easily overlooked. Interestingly, the colourful shell patterns show an enormous number of variations, no two shells being identical. They feed on detritus and algae, prefering slow moving, sheltered, shallow waters. (Shell 0.3-0.5cm).
