Plait (gastropod)
From Wikipedia, the free encyclopedia
In gastropod molluscs, plaits are folds on the columella (also known as the pillar or axis). The columella is the central structure around which the whorls of a coiled gastropod shell encircle.
Plaits are characteristics used in the description of many gastropod molluscs, often enabling similar species to be correctly identified.
