Clams and fancy armor is not the same, the specific differences are as follows:

1, the shape is different: they have a different pattern of armor. Clams are shaped like a triangular oval or ovoid, the surface is relatively smooth or concentric growth lines, but the inner edge of the clam shell flat and sharp. The flower nail shape like oval, smaller, the surface of the color is generally yellow-brown, the shell surface also has a dark pattern, feel a hint of bumpy feeling.

2, the texture is different: the meat of the clams is more firm, while the meat of the flower armor with a little sheep feeling.

3, different living areas: clams generally live in the deep sea area, the flower armor generally live in the shallow sea area.

4, the origin of the distribution of different: clams are Qingdao, Dalian, Yantai, Weihai and other coastal cities unique seafood, flower armor in the Red Sea to Australia and Japan, China distribution coast are distributed.

Clams Introduction:

Shells and other large, triangular ovoid or ovoid, most species on both sides of the unequal. The shell is usually thin, some species have both shells closed, most species have one end open or both ends open, often with a shell skin; the shell surface is smooth or with concentric growth lines, the inner edge of the shell is flat and sharp. Shell apex mostly prominent and anteriorly inclined. The crescentic and tatty surfaces are usually clearly demarcated.

The margin of the shell apex has an outer ligament and another ligamentous groove in which the inner ligament resides. Articulated left shell with a split primary tooth, inverted "v"-shaped, usually fused apically, with the posterior branch of the primary tooth immediately adjacent to a parapleuron; right shell with the primary tooth usually separated. Right and left shells with lateral teeth, single in left shell, double in right. Outer sinus usually deep, rounded or angular, with a long water tube, fused at the end.
