Symmetry of a clam.

Bilateral symmetry- they have definite left and right halves, and only a single longitudinal cut down the centerline of the animal produces two equal halves. Bilaterally symmetrical animals have defined anterior and posterior ends, and forward movement is guided with the anterior end. Crab, human, turtles, fish, birds, giraffe, wolves. Clams, Snails, and Squid: Phylum Mollusca, Class Pelecypoda. Pelecypods have two shells, or bivalves, that protect the soft parts of the animal.

Lamp Shells: Phylum Brachiopoda. Brachiopods are shelled invertebrate that look somewhat like bivalved molluscs.

Shell Symmetry and Representation. Gastropods such as Conus are not bilaterally symmetrical, that is, as the snail grows, its shell coils about a vertical axis.A clam is a bivalve mollusc that has a soft body enclosed by two hard shells. Clams are found in marine habitats all over the world. Most clams live buried in sediment, and feed by filter-feeding. Clams have a radial symmetry, meaning that their body can be divided into equal halves by any number of radial lines that pass through their center ...Symmetry is important because it is the main feature of nature that restricts the permissible dynamic laws. The concept of balance is very important to understanding how symmetry works.Unmodified beaches nearby clam gardens are, by contrast, primarily composed of silt, sand, and mud (Jackley et al. 2016).

( Ensis ensis) Bivalvia ( / baɪˈvælviə / ), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts.Shell. The generally accepted systematic name (in contrary to some others) of all mussels, clams and scallops - Bivalvia - the two-valve molluscs - refers to the most important character of all bivalves, that separates them from all other molluscs: The shell is separated into two pieces.

Clams are filter feeders, and they use their foot to dig into the sediment at the bottom of the ocean to find food. Clams have a symmetrical body, and their shells are also symmetrical.

Each valve of Nuculopsis (right drawing, “Bilateral symmetry (clam)”) is nearly a mirror image of the other, so that the plane of symmetry lies along the line at which the valves join, called the line of commissure. This is true of most clams. Brachiopods are quite different.Members of the phylum Mollusca are soft-bodied animals, such as the snail, clam, squid, oyster, and octopus. Generally, these animals live in water.The clam's history with introduction into England has shown that deliberate introduction of a species has the capability of working commercially (Mercenaria mercenaria 2000). The Algonquin tribes would grind up the shells and make beaded necklaces that would be used as wampumpeag or wampum, which means money (Grzimek's 1974). Symmetry of roundworm. bilateral.

Bivalves are molluscs with bodies that are enclosed in a shell of two halves (valves) that can be opened at one end. The animal pumps water in and out of the shell. This water brings dissolved oxygen for the animal to breathe with gills and, in most species, food particles. Bivalves can be found in fresh water or saltwater environments.

The clam has no head, and usually has no eyes, (scallops are a notable exception), but a clam does have kidneys, a heart, a mouth, and an anus. Clams have bilateral symmetry. Clams, like most mollusks, also have open circulatory systems, which means that their organs are surrounded by watery blood that contains nutrients and oxygen.Terms in this set (39) what is symmetry. how the body parts are arranged on an organism. what are the three types of symmetry. asymmetrical radial & bilateral. what is asymmetrical. does not have a distinct arrangement of body parts. what is radial JH. the body parts in the animal radiate from one central point like a spokes on a wheel.
