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

The common types of radial symmetry for fossils in this chapter are 5-fold radial symmetry (pentamerous) and 6-fold radial symmetry ... bilateral symmetry (hence the name); that is, dorsal-ventral and left-right axes; triploblastic (three tissue layers: ectoderm, mesoderm, endoderm) HOX genes in one or more clusters with the genes within a cluster arranged in the same order as the body parts they affect. The bilaterians contain two clades, the protostomia and the deuterostomia.Cephalization is defined as the evolutionary trend toward nervous system centralization and the development of a head and brain. Cephalized organisms display bilateral symmetry. Sense organs or tissues are concentrated on or near the head, which is at the front of the animal as it moves forward. The mouth is also located near the front of …. In bilateral symmetry, you create two matching halvClam support system. shell. Clam segmentation. No segmentation. Clam a 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 ... Clams are filter feeders. Water and food particles a 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 ...Which of the following animals have bilateral symmetry? A. Jellyfish (Cnidaria) B. Starfish (Echinodermata) C. Bee (Arthropoda) D. Earthworm (Annelida) E. Sponge (Porifera) F.
