The fossil record of this species dates back to the Miocene (age range: 13.65 to 0.012 million years ago). These fossils have been found in Morocco, the Netherlands, Spain, Italy, United Kingdom and Slovakia.[4]
The rounded shell is thin and polished and brownish-yellow, with a row of reddish markings just below the suture of the last whorl. It can grow to about 3 cm (1 in) and has a short spire and seven rounded whorls separated with distinct sutures. The lowest whorl occupies about 90% of the volume. It has a large umbilicus and the operculum is ear-shaped and spirally wound.
The foot is cream coloured and very large, partially covering the shell when the animal is moving. The head has two long flattened tentacles and a short snout with extensible proboscis.
The large necklace shell might be confused with a similar but smaller species, the common necklace shell (Euspira pulchella).[5][2]
The large necklace shell is found on the coasts of Northwest Europe, from the Mediterranean Sea to the Skagerrak and in the Northeast Atlantic Ocean.[6]
The large necklace shell lives buried in the sand and gravel of the lower shore and the neritic zone to depths of 125 metres. It feeds on bivalve molluscs, penetrating their shells with its proboscis and sucking out the contents.[2]
Egg capsules are laid in a spirally wound collar of jelly embedded with sand grains. The remains of these may be found on the beach.[2]
