Jujubinus striatus
Jujubinus striatus, commonly known as the grooved top shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.
Subspecies include:Jujubinus striatus delpreteanus
- ''Jujubinus striatus striatus''
Description
The size of the shell varies between 6 mm and 13 mm. The small, imperforate, solid shell has an elongate-conical shape. It is brown or yellowish olive, rarely unicolored, striped or lined longitudinally with white, sometimes the striping broken into a tessellated pattern. The surface is dull or shining. The whorls show a much less prominent ridge at the periphery than in Jujubinus exasperatus. The supra-sutural fasciole when discernible, is not projecting nor prominent. The whorls are encircled by numerous subequal lirulae. The interstices are slightly or strongly obliquely striate. The base of the shell contains numerous striae or riblets, about double the number possessed by Jujubinus exasperatus.
This species is distinguished from Jujubinus exasperatus, a species of nearly the same size and outline, by its finer more numerous spiral striae, and a less strongly truncate columella.
Distribution
This species occurs in the English Channel, the Atlantic Ocean from France to the Azores and the Canary Islands and Madeira; and in the Mediterranean Sea. In the Irish Sea it was recorded in the Langness Marine Nature Reserve off the Isle of Man in 2019; the first Manx record since Edward Forbes first recorded there it in 1838.
