The Euspira Montagui or unspotted umbilical screw ( Lunatia montagui ) is a screw from the family of the moon screw extending from molluscs fed. It lives in the North Sea , the northeast Atlantic and the Mediterranean .
features
The rounded snail shell of Lunatia montagui , which in adult snails with 4 to 5 whorls usually reaches up to 9 mm, sometimes up to 14 mm in length and width, has a rather low thread with stepped whorls and incised seams between the outer lip and the circumference of the body forms a notch. A pit leads from the partially closed umbilicus over the inner lip to the housing mouth. The surface is yellowish to reddish with a narrow white band under the seam and without any further housing markings.
The animal is creamy white, the rear edge of the propodium is brown. In the active animal, the large foot covers the head and part of the housing. The propodium is used to plow through the sandy subsoil.
distribution
The immaculate moon snail occurs in the north-eastern Atlantic , in the North Sea to Norway and in the Mediterranean , and also in the Baltic Sea .
habitat
Lunatia montagui lives on sand and muddy bottoms at depths of 15 to 200 meters, mostly below 30 meters.
nutrition
Like other moon snails feed on Lunatia montagui of clams and snails that are sought by digging his foot in the sand. The prey is grasped with the foot and a hole is drilled in the shell with the radula .
