Characteristics of the Carril Clams
Clam is the name of a big number of bivalves, that live both in the sea, as in fresh water. They have a flattened body, and two shells attached to their backs; that have the function of protecting their body by covering them.
For this reason they are called bivalves, because this means that they have two valves joined together; and they are mollusks, because their name comes from the Latin, molluscus, which means soft. Then, the Carril clam, is a soft body; which is covered by two valves that are joined together, and have symmetrical shape.
Moreover, the shells of the clams are hard and calcareous; and are usually very similar to each other. The Carril Clams, are characterized by the radial lines that can be observed on their shells, which makes of them very easy to be distinguished from others species of clams.
In certain sectors of the shell, these lines are usually very pronounced, and when they cross each other; they form grids that no other clams have.
For example, the surface of the slug clam , is much smoother; and the radial lines are difficult to distinguish.
In general, the shells or valves of the clams are oval; even they could have a rectangular shape, since they usually form two parallel lines between both pieces . However, the Carril´s Clam is more rounded, which makes it different from others clams.
The rounded shells of the Carril Clams, are stuck together by a ligament composed of an elastic protein. They also have a sort of teeth and channels, both in the upper shell and in the lower one; which prevent them from moving or opening, leaving the body of the clam exposed. Although, it doesn´t look like it, the shell of the Carril Clams is thin, and has, like all the other clams; a dorsal protuberance that receives the name of umbo. As we mentioned before, it is convex and has a number of fine striae , that besides being easy to visualize, they are also easily felt when touched.
In general, clams can have different colors, ranging from dark gray, through brown spots, and reaching the lighter gray. However, Carril Clam has a creamy coloration, that ranges between yellowish and brown; with certain darker marks; which is another distinctive characteristic of these mollusks .
All these mollusks have a scarcely developed, head and sensory organs. However, Carril´s Clam despite their lack of eyes or brain; have a split syphon (bifid siphon) unlike the rest of these mollusks . They also have gills, which they use to perform gaseous exchange, and to filter their food.
The organs of the Carril Clams are surrounded by blood and water, which provide them all the nutrients of the oxygen.
The dimensions of the Carril Clams are variable. There are specimens that measure between nine and eleven millimeters, while others can measure between fifteen and eighteen millimeters. They weigh between twenty and forty grams. Their bodies are composed of visceral mass, a reproductive system, a digestive system, an excretory system, the heart, the foot, and the head.
The siphon, the oral apparatus, the teeth, and the foot they use to move, are located on the head of the clam. They also have a mantle produced by their shells; where the breathing of this mollusk takes place.
