Assiminea grayana

This species lives in habitats that are intermediate between land and saltwater: in estuaries and salt marshes, at, or right above, the high tide level.[1]

The 5 mm high x 3 mm. wide shell is semi-transparent and conical, with six or seven flat-sided or slightly swollen whorls and a sharp apex. It bears fine irregular growth lines and faint spiral lines but appears smooth . The oval or ear-shaped aperture is small and has a thickened peristome. The inner lip is reflexed over the base of the last whorl. There is no umbilicus. The colour is horn or tan, often with a broad reddish band on the last whorl.

This small snail lives in Western Europe, primarily on the southern part of the North Sea coasts, in countries and islands including:

• Great Britain
• Ireland
• The Netherlands

This species reproduces sexually. The male has a penis in the middle, or at least close to the middle, of his head. The female has a series of translucent glands the lead to a seminal receptacle, where an egg waits for the semen.[2]
