What type of symmetry do molluscs have?
bilateral symmetry
Mollusks have bilateral symmetry. – The two halves of the body mirror each other. Gastropods (snails) ~ eat with a radula (tiny tongue covered with teeth.
Does a shell have symmetry?
Gastropods such as Conus are not bilaterally symmetrical, that is, as the snail grows, its shell coils about a vertical axis. But it does when the shell is not symmetrical, as it is with the coiled shells of snails. …
Do clam shells have symmetry?
Differences in Shell Symmetry Bivalves have a plane of symmetry that cuts between their two valves. They have symmetry similar to our hands. Bivalves are often described as having left and right valves. Brachiopods have a plane of symmetry that cuts across the two valves.
Do molluscs have radial symmetry?
These creatures are radially symmetrical, meaning all their appendages emanate outward from a central point. Most mollusks, on the other hand, exhibit bilateral symmetry.
What is the symmetry of Arthropoda?
Arthropods that live on land have a series of tubes throughout their body called a tracheae. Arthropods are bilaterally symmetrical, that means that if you sliced them from top to bottom, each half would be exactly the same!
What type of symmetry does a fish have?
Bilateral symmetry
Bilateral symmetry is characteristic of the vast majority of animals, including insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans.
Are sea anemones symmetry?
Sea anemones, named after a terrestrial flower, have a basic radial symmetry with tentacles that surround a central mouth opening.
What type of symmetry do clams have?
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 most clams.
What is the symmetry earthworm?
Earthworms have bilateral symmetry. This means that if you cut the earthworm down the centerline, the left side of the body would be identical to the right side.
