Pinna is a
genus of
bivalve
molluscs belonging to the family
Pinnidae .
[2]
The
type species of the genus is
Pinna rudis .
The most completely studied species in the genus is
P. nobilis , a
Mediterranean pen shell which was historically important as the principal source of
sea silk .
Description
Pinna noblis shell & byssus.
Shell.
These pen shells can reach a length of about 80–90 cm (31–35 in). They are characterized by thin, elongated, wedge-shaped, and almost triangular shells with long, toothless edges. The surface of the shells shows radial ribs over their entire length.
Pinna is distinguished from its sibling genus
Atrina by the presence of a
sulcus dividing the
nacreous region of the valves, and the positioning of the
adductor scar on the
dorsal side of shells.
These
bivalves most commonly lie point-first on the sea bottom in which they live, anchored by a net of
byssus threads.
Distribution
Species in the
genus Pinna are geographically widespread. This genus is very ancient, going back up to the
Carboniferous period. It is especially represented in
Jurassic and
Cretaceous
fossils .
