Snails' bodies have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side. Their shell, on the other hand, tends to be radial symmetry.
Porifera is the phylum with no body symmetry: it is asymmetrical.
Bilateral Symmetry
Birds, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
This is radial symmetry. Animals with radial body symmetry display a regular arrangement of body parts around a central axis, usually in a circular pattern.
Penguins, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
Of course,gastropods [eg:-snail] do not show any symmetry
Gastropods have a closed-circulation because it has ventricles that carry blood throughout it's body.
How can you identify the body symmetry of an animal
Sand dollars are not gastropods. Gastropods are charecterized by having a soft body with or without shell. Gastropods comes under phylum mollusca and sand dollars comes under phylum echinodermata.
Porifera is the phylum with no body symmetry: it is asymmetrical.
Some mollusks have bilateral symmetry. Mollusks include gastropods such as snails, bivalves such as oysters, and cephalopods such as squid. Some bivalves have bilateral symmetry.
yes, they have bilateral symmetry
yes! he has bilateral symmetry.
Bilateral Symmetry
Using good posture can improve your body symmetry.
If a animal has a head then its body symmetry is bilateral.
