Many invertebrates such as insects, arachnids and other arthropods 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.
However, some invertebrates such as jellyfish have radial symmetry. Animals with radial body symmetry display a regular arrangement of body parts around a central axis, usually in a circular pattern.
Vertebrates in general have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down

Nervous tissue is composed of neurons that use electrical signals to transfer impulses throughout the body.
This is called bilateral symmetry. Bilateral symmetry means an organism has 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 seen in all vertebrates, and many invertebrates such as arthropods.
Bilateral, meaning left and right are equal.

Turritopsis is a type of jellyfish. All jellyfish have radial symmetry, which is when the symmetry is arranged in a circular pattern, like a wheel, for example.

Rhinoceroses have like all vertebrates, have bilateral symmetry.

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.
A slice of lemon displays radial symmetry. This type of symmetry is typically seen in jellyfish and sea anemones.
