Turbonilla internodula
Habitat: it lives in the infralittoral and circalittoral zones on detrital-muddy bottoms.
Distribution: it can be found all over the Mediterranean. Always rather rare. collected at Punta della Mona, Malaga (Spain), at 40 m depth.
Notes: shell solid, conic in outline, whorls flat-sided and angularities missing, suture inclined. Typical colour pattern: uniform deep pink in colour. Sculpture made by axial ribs strong, orthocline, wider than interspaces, crossed by one spiral cord only placed in the median part of whorls and visible in the interspaces only where it makes some nodulosities. Aperture has got a columella straight and a bell-shaping in the lower part. Colour, typical spiral sculpture as well as geographical distribution make this species easily recognizable from its similar ones. Protoconch type B. Juvenile specimens are easily definable due to their typical colour pattern and owing to their strong spiral cord. Turbonilla rosea (Monterosato, 1877) is considered as a synonym of this species. Average measures of adult specimens can reach 6 mm in height.
