|Researched by||Anna Neish||Refereed by||Admin|
|Other common names||-||Synonyms||Cantharidus striatus , Trochus striatus (Linnaeus, 1758)|
Recorded distribution in Britain and IrelandLocally abundant in the Channel Islands but rare on the British and Irish coasts. There are records from south Devon, the Isle of Man and the Isles of Scilly, but recent records only from Bognor Regis, Falmouth, and Bryher in the Isles of Scilly.
Global distributionDistributed from the Mediterranean northward to south-west Britain.
HabitatAt low water spring tides down to 300 m. Usually found around plants and seaweed especially Zostera marina, and on stones among Ulva and Codium species.
- A pyramidal shaped top shell up to 10 mm high and 8 mm broad.
- Shell consists of 6 whorls, the last whorl relatively large.
- 8-10 smooth concentric ridges between keel and adapical suture on the last whorl and 7-9 ridges on its base.
- Relatively large, obliquely oval aperture, usually pink.
- Variable shell colour but usually brown and cream which can form alternating bands or a chequered pattern.
- Apical region of shell can be a carmine red colour.
- Umbilicus closed in adults.
- The foot has 3 pairs of epipodial tentacles.
Additional informationJujubinus striatus is very similar to Jujubinus exasperatus which is one of three other species of Jujubinus recorded in Britain although none is common. Jujubinus striatus has apparently disappeared from many sites where it was formally common as there are no recent records.
