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.Annelids display bilateral symmetry and are worm-like in overall morphology.

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 ...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.What Type Of Symmetry Do Clams Have by Harley Gutiérrez | Mar 7, 2023 | Clams Clams are marine mollusks that are related to snails, slugs, and mussels.

True or False: Honeybees are important pollinators of a large percentage of our crops.$\begingroup$ @ d_b, thanks for the comment. My confusion arises exactly from your point. I thought when we say we have a gauge theory we have a theory with a local symmetry and the gauge fields are the connections of the Lie group but then I came across the following paper.There, we have a color vector charge $\vec{q}$ with a global SO(3) symmetry in color space and gauge symmetry for the ...Clams with a tightly closed shell are alive and can be safely eaten.
