$\begingroup$ @ d_b, thanks for the comment. My confusion arises exactly from your point.

An internal symmetry is a transformation acting only on the fields, therefore not transforming spacetime points, and leaving the lagrangian or the physical results invariant. Example of internal symmetries are gauge symmetries. These are local symmetries, which means the transformations are in general spacetime dependent in the sense they are ...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) …Clam is an imprecisely defined common name variously used for certain bivalve mollusks or for all bivalve mollusks. As a member of the class Bivalvia (syn. Pelecypoda), clams typically are characterized by two-part calcareous shells that are hinged and more or less symmetrical and a laterally compressed muscular foot, which when extended into sediment (sand or mud), can swell with blood and ...symmetry tissue organization body cavity openings into the digestive tract circulatory system habitat organs for respiration organs for excretion type of locomotion support systems segmentation appendages type of nervous system. three types of body cavities. acoelomate - three layered, ...Identify the body symmetry, segmentation, and skeletal system of the major animal groups (pig & rat), Crayfish, Grasshopper, Annelida (earthworm), Starfish, Squid, clam, and hydra. Body Plan The body plan of an organism is the sum of all structural traits of an organism.Class Bivalvia ranges from Lower Cambrian to today, and peaked in the Cenozoic. 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).

These body shape changes are either symmetrical or asymmetrical in time. Examples include the cyclic extension/contraction adopted by the Atlantic razor clam ...

What are two …Brachiopod shells are probably the most commonly collected fossils in Kentucky. Brachiopods are a type of marine invertebrate (lacking a backbone) animal. Their shells have two valves attached along a hinge, similar to clams. Although they had two shell valves protecting soft parts inside, as clams (bivalves, pelecypods) have, all similarity ...Chapter contents: 1.Brachiopoda –– 1.1 Brachiopod Classification ← –– 1.2 Brachiopods vs. Bivalves –– 1.3 Brachiopod Paleoecology –– 1.4 Brachiopod PreservationAbove image: Kunstformen der Natur (1904), plate 97: Spirobranchia by Ernst Haeckel; source: Wikimedia Commons (Public Domain).Overview With very few living representatives, brachiopod …Clams, Mussels, Oysters, Scallops, Shipworms. Morphology. ... 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.Mollusca can be found in freshwater, marine and terrestrial habitats. More features of molluscs include bilateral symmetry, soft or unsegmented bodies, respiration via ctenidium, ganglia/nerve comprised …Inside of the clam shell (use shucked clam): 1) Identify anterior and posterior ends, and the dorsal and ventral sides of clam shell below. 2) Locate the following on the clam shell below and record on blank lines provided: anterior and posterior muscle scars, umbo, hinge ligament and teeth, mantle attachment, and small teethThe 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.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) Shell

It is estimated that 23 percent of all known marine species are mollusks; there are over 75,000 described species, making them the second most diverse phylum of animals. 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.

A body plan is a stable configuration of characters for a major taxonomic group, such as chordates or arthropods.
