Clam symmetry.

Food is processed by the digestive system which includes the stomach, intestines, rectum and anus. The excurrent siphon carries away the water, disregarded (non-food) particles and waste. Discarded waste material processed through the digestive system into the water column is called feces.Bivalvia Bivalvia –– clams, oysters, scallops, musselsclams, oysters, scallops, mussels Class Bi l iBivalvia –20,000 described species Clams Oysters Scallops Mussels Shipworms Bivalve form Two valves, halves , or shells Coquina Giant Clam Bilateral symmetry ‐both sides the same size Compressed laterally (sideways) ShellThe combination of bilateral symmetry, a true coelom, and segmentation created new possibilities for organisms. Further specialization could now take place along the sides of the cephalized and forward-moving animal body. The success of the arthropods and also of the chordates are the end result of this evolutionary breakthrough.Summary Table of Animal Characteristics.

Water and food particles are drawn in through one siphon to the gills where tiny, hair-like cilia move the water, and the food is caught in mucus on the gills. From there, the food-mucus mixture is transported along a groove to the palps (mouth flaps) which push it into the clam's mouth.One shape that has at least one line of symmetry is a rectangle. A rectangle has two lines of symmetry. Line symmetry,is also known as reflection symmetry.

Brachiopods have valves covering the top and bottoms of the animal that are of different sizes and shapes, but the left and right sides are are symmetrical (or mirror images to each other).Radial Symmetry. Another trait that evolved early on was symmetry. To understand symmetry, you need to see an animal that lacks symmetry. A sponge, like the one in Figure below, lacks symmetry.

The gills also draw oxygen from the water flow. From there, the cilia move the particles along food grooves toward the labial palps, where they are sorted. linguistics constituency tests Animal body plans follow set patterns related to symmetry. They are asymmetrical, radial, or bilateral in form as illustrated in Figure 33.2. Asymmetrical animals are animals with no pattern or symmetry; an example of an asymmetrical animal is a sponge. Radial symmetry, as illustrated in Figure 33.2, describes when an animal has an up-and-down orientation: …Grooves or ridges on clams are very fine and appear as lines oriented symmetrically around the shell like a modern clam, rather than across it, as is common in many brachiopods.
