Clam symmetry.

By Almandine via Wikimedia Commons. Clams live in the water near the edge of the ocean and spend most of their time buried in the sand. The quahog (pronounced co-hog) clam grows two large shells that it holds together with a strong muscle. The quahog can open its shells to look for food and close the shells completely if it is feeling threatened.Verified questions. physical science.

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. This means it cannot be divided into two identical halves. A symmetrical organism, in contrast, can be divided into two identical halves.

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 ... This is true of most clams. Brachiopods are quite different. Inasmuch as their valves are seldom similar, the plane of symmetry that divides the animal into mirror-image halves passes vertically down the middle of each valve (left drawing, "Bilateral symmetry (brachiopod)"), and is perpendicular to the line along which the valves join.Clams, Snails, and Squid: Phylum Mollusca, Class Pelecypoda.

Symmetry in the arrangement of body parts is a distinctive phylogenetic feature of animals. Cnidarians show both bilateral and radial symmetries in their internal organs, such as gastric pouches ...Clams are filter feeders. 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.anyway back to the beach. Bilateral symmetry can be easily found on shells if you are lucky enough to find any type of clam style shell that is still attached to its other half. These are often referred to as 'Bi-Valve'; having two halves. Many leaves will show a tendency towards bilateral symmetry because of the presence of a mid vein.GLY 3105C Lab 5 – Introduction to Paleontology 6 Part 2: Symmetry in Fossils Identifying the symmetries found in different fossils is useful in identifying the organism that formed them. Symmetry itself is defined as a pattern seen in shapes in which two halves across an axis show similar size, shape, and structures. There are three main …Bilaterians are animals that have bilateral symmetry, meaning that they can be divided into equal left and right halves.
