The second species had previously been considered to be simply a form of N. duplicata, but it is now recognized as Neverita delessertiana.
The shell has a flattened globular shape, and reaches about 88 to 90 millimetres (3.5 to 3.5 in) in maximum dimension.
[3] This moon snail is found on sandy shores just below the low tide line.
In most of its range, the empty shell is very commonly washed up on beaches, as also is the operculum and the sand collar.
This snail drills a neat "countersunk" circular hole through the shell of its prey species, and then feeds on the soft tissue within.
