Morphology. The pelecypods are a type of mollusk that has two shells, hence the common name of bivalves. The shells are hinged together by a ligament that continually forces the shells open. Only special muscles, called adductor muscles, can close the shells together. ٢٣‏/٠٨‏/٢٠٢٢ ... More features of molluscs include bilateral symmetry ... Visible among the many aspects of an open clam are the posterior and anterior adductor ...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).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.What type of symmetry do clams have?

Representative Animals: Snails, Octopus, Clams. Habitat: Species of phylum Mollusca can be found in saltwater, freshwater and on land. Reproductive System: Animals in phylum mollusca reproduce sexually. Some species are dioecious whereas others are hermaphroditic. Many species have internal fertilization and produce eggs.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).The line drawing below is helpful in illustrating the differences in symmetry between pelecypods and brachiopods. 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 ... 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).

Certain characteristics will become obvious immediately. Can you determine symmetry, support systems, and the presence or absence of appendages? Are there external signs of segmentation? A clam's shell is it's symmetry. when the clam opens up it's shell each side of the shell is equally the same on both sides. This is what is called symmetry.Bivalves vs. brachiopods. Bivalves and brachiopods are both types of “sea shells.” both have shells composed of two valves, but the organisms inside the shells are quite different. Typically, the two valves of a bivalve are mirror images of each other (termed equivalved). Their valves are symmetrical along a plane through the hinge.Echinoderms. Echinodermata are named for their spiny skin (from the Greek “echinos” meaning “spiny” and “dermos” meaning “skin”).

Further specialization could now take place along the sides of the cephalized and forward ...Body Plan. In a typical sea star, it is easy to see the classic five-fold symmetry that is characteristic of echinoderms. This includes arms projecting outwards around a centralized axis. Even sea cucumbers, which show a more worm-like appearance, usually exhibit this body plan, known as pentameral symmetry.Leukoma staminea.

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.Classes in Phylum Mollusca Gastropoda - snails Chl d Cephalopoda –squid tids, octopus Polyplacophora - chitons Scaphd hopoda –tusk h llk shells Bivalvia Bivalvia –– clams, oysters, scallops, musselsclams, oysters, scallops, mussels THE SYMMETRY OF A CLAM. A study. There’s an intimacy in photographing shellfish and so much to explore in their structures. I could spend hours on them. Most of you know by looking at it that a clam’s shell is a far cry from the oyster’s shell. A clam’s structure is called “bilateral symmetry,” meaning two sides are mirrored halves.The word mollusk means soft-bodied, but when we think of many of the commonly known mollusks, such as clams or snails, it is the hard outer shell that is the most obvious feature.

The valves of a clam are the two cupped shells that form the clams hard outer covering These shells are joined by a single ligament.
