The Yellow peppers mussel ( solemya togata) , even pods shell called, is a shell - type in the family of solemyidae (Solemyidae) from the order of Solemyida .

features

The housing of the yellow shellfish, which has the same flaps, is elongated with largely parallel ventral and dorsal edges. It is rounded at the back and front, and gapes at both the back and the front end. The small and almost colliding vertebrae are shifted towards the rear end, i.e. H. the housing is very unequal. The maximum length is about six centimeters. There is no lunula , but the area is comparatively large. The edges of the area are clear, the area itself is convex. The edge of the case is quite sharp and is formed on the front, ventral and rear edge by the periostracum protruding far beyond the mineral shell . The ligament lies internally between and behind the vertebrae. The lock is toothless.

The whitish mineral skin is thin and fragile and consists of two aragonitic layers with different microstructures . The comparatively thick organic periostracum adheres firmly to the mineral shell. The periostracum is light brown, dark brown to red brown with dark or greenish radial bands. The surface (of the periostracum) is smooth and shiny. When the casings are dry, the protruding periostracum is often torn or even partially broken off to the edge of the mineral shell.

The two sphincters are unequal in size; the anterior is significantly larger than the posterior sphincter. The surface line is not indented, often overgrown and indistinct. The water flows in through the front end.

Geographical distribution and habitat

The distribution area of ​​the mussel stretches in the eastern Atlantic from northern Spain to Senegal and the Cape Verde Islands . It is also found in the Mediterranean . It lives in muddy or sandy soils from very shallow water to a depth of about 30 meters, in the Mediterranean often between Neptune grasses ( Posidonia ) and in the Zostera marina community.

Taxonomy

The species was proposed by Giuseppe Saverio Poli in 1791 in the combination Tellina togata . It is de facto the type species of the genus Solemya Lamarck, 1818, since the formal type species, Solemya mediterranea Lamarck, 1818 is a younger synonym of Tellina togata Poli, 1791. The MolluscaBase names the following synonyms: Mytilus solen Salis, 1793, Solemya lamarcki Gray, 1858, Solen prunneri Küster, 1833, Solenomya mediterranea Lamarck, 1818 and Stephanopus polianus Scacchi, 1836.
