Distribution

The distribution of Parmacella valenciennii includes:

Description

The animal is brownish red to brownish olive, with black bands on the mantle.[2] Adult specimens are lighter.[2] The body is sharply keeled in the posterior section.[2] The mantle length in young animals is about 3/4 of the body length.[2] The mantle is rounded in the anterior part and pointed in posterior part.[2] The animal is up to 100 mm long, usually 70–80 mm long and 20 mm in width.[2]

The shell is yellow, triangular, fragile and flat, with 1.5 whorls.[2] The length of the shell is 15 mm, 9 mm in width and 2–3 mm high.[2]

Parmacella valenciennii differs anatomically from all other Parmacella species by a single, characteristically horn-shaped and almost straight accessory atrial appendix.[2]

Ecology

Parmacella valenciennii lives in stony open habitats, preferring shady and humid sites between plants and stones.[2] The animals move slowly.[2]

There is a high abundance of these animals in the spring;[2] the animals were so abundant that they were formerly used as pig food in southern Portugal.[2]
