A drift of sea-snail shells
A collection of washed-up shells on a beach on the south island of New Zealand. Shore transport processes have produced a well-sorted drift of similarly sized (approx. 1-2 cm) shells and shell fragments. The main species represented are the common turret shell (Maoricolpus roseus) and wheel shell (Zethalia zelandica), both sea snails endemic to New Zealand.
