Clam symmetry.

The numbers of littleneck clams began declining in the 1990s due to environmental impacts such as food availability, disease, and climate change.

Bivalve animals are typically encased in two shells—also called valves—hence the name bivalve. The shells have bilateral symmetry from top to bottom (the two shells look the same), rather than the side-to-side symmetry of the brachiopods (Figure 7.10).

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). A body plan is a stable configuration of characters for a major taxonomic group, such as chordates or arthropods. Despite widespread casual reliance on the concept for guiding comparisons within and between groups, the nature of body plans as well as the biological causes underlying their evolution have remained elusive. This paper proposes …The location where the two valves of a brachiopod or clam come together. See symmetry figure. Concavo-convex. One valve of a brachiopod is rounded outward outward as the surface of a ball, and the other valve is depressed inward as a bowl. Concentric. Having the same center. A bullseye is an example of concentric circles. Concretion.The shells have bilateral symmetry from top to bottom (the two shells look the same), rather than the side-to-side symmetry of the brachiopods (Figure 7.10). Figure 7.10 | Examples of Class Bivalvia. Bivalves feed by sweeping food out of the water column and drawing it through the shell; for most bivalves this food is phytoplankton. Food is caught in mucus produced by the gills. 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.Summary Table of Animal Characteristics.

Bilateral symmetry and cephalization; Sensory, feeding structures at one end; Reduced cross-sectional area; Good for burrowing, getting into protective crevices, insinuating into tissue spaces of organisms (parasitism) Large surface area/volume; Gas exchange, waste removal, nutrient uptake; Elongate digestive tract The clam also contains a set of long siphons, which stretch from the clam's mantle, the membranous sac that contains the internal organs and constitutes the body of the clam, to the surrounding medium outside of the shell (Plourde 2001). It uses these siphons for respiration and gathering food. ... having body symmetry such that the animal can ...Internal symmetry is an actual symmetry of the system (field): two physically distinct field configurations (or in QM, two physically distinct states in Hilbert space) are related via an internal symmetry operation. However, the gauge "symmetry" is not an actual symmetry of the physical system. Two states which are related via a gauge ...Bivalve - Gills, Filter Feeding, Mantle: Primitive bivalves have paired gills that are small; in most other bivalves the gills are greatly enlarged. The vascular system contains the heart comprising a medial ventricle with left and right auricles. The reproductive system is simple. The most significant adaptation is the shell with two valves that wholly contains the animal.Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related. Instead of being horizontally symmetrical along their hinge, like clams and other bivalves, they are vertically symmetrical, cut down the middle of their shell.

Magellania venosa is the largest extant species. The largest brachiopods …The difference is found in their respective symmetries. Bivalves are symmetrical with respect to their hinge line while brachiopods have a line of symmetry perpendicular to the hinge line, that is, the left of the top and bottom shells is identical to the right of the top and bottom shells. Like all mollusks, bivalves have a foot. aquifer system However, in general, clams tend to have radial symmetry, meaning that their bodies are arranged around a central point. This symmetry helps them to filter food and water efficiently from all directions. The body of a starfish or sponge is divided into two symmetrical halves or lobes, each with its own set of characteristics. It is due to the ...Diversity. The phylum Brachiopoda, also known as lamp shells, is a group of bilaterally symmetrical, coelomate organisms that superficially resemble bivalve molluscs.Approximately 450 species of living brachiopods are currently known, and have traditionally been divided into two classes: Inarticulata (orders Lingulida and Acrotretida) …Figure 1: Shell symmetry is seen as how similar in dimensions a shell is in both directions away from its center. For example, symmetry can be determined by looking at the length of the two heavy lines drawn from the center of this Tridacna squamosa shell.
