lamella

or

thylakoid

a thin layer or plate. The term is used in the plural (lamellae) for:
  1. the sheet-like membranes that occur within the CHLOROPLAST, each of which consists of a pair of membranes with a narrow space between. Some 3000 occur in each chloroplast and their function is to maintain the CHLOROPHYLL molecules within the quantasomes in such a position as to receive the maximum amount of light.
  2. the gills of a basidiomycete fungus that radiate out from the stalk beneath the cap of the fruit and bear the spores.
  3. the layers in which the calcified matrix of bone occurs, each some 5 μm thick.

Functional significance of lamellose axial shell sculpture
Although we did not specifically measure withdrawal depth, we believe that our assumption that lamellose and artificially smooth snails would have similar withdrawal depths is warranted for two reasons.
Naturally smooth shells had a naturally shorter shell length than lamellose shells when matched by width, which also suggests that size may be a factor.
Our results add an important new piece of evidence for the adaptive nature of this plasticity: in habitats where shell-breaking crabs are rare, thin shells with lamellose sculpture may be less vulnerable to predation by sea stars.
