Radial symmetry is uncommon in land animals because unlike seagoing creatures their habitats are far less threatening.
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.

A radial tire is different from a normal tire in that a radial tires athatre built to last longer. The main difference is that radial tire have wires or cords that radiate at a 90-degree angle from the tire rim.
A multi radial wheel is a wheel that can multiply itself and it is radial
Picture the center of a circle. The distance from it to the edge of the circle is the radius. The fixed distance from the center to the edge of any part of the circle is radial movement. So radial movement is the circular distance an object can move from a fixed point.
All life on land evolved from a few aquatic ancestors. It just so happens that all of these ancestors were not radially symmetrical, so all land animals are not radially symmetrical.
Radial symmetry.other animals (exept sponges) and other exeption have bilateral symetry. bilateral symmetrical animals have up and down side, and a front and a back leaving left and right the same. radial animals only have an up side and down side, they do not have a fornt and back side.radial symmetry
One animal that has radial symmetry is a sea sponge.
Jellyfish are ocean animals with radial symmetry.
sponges have no symmetry animals with radial symmetry are radiata and cnidaria, like jellyfish
Radial symmetry - jellyfish, starfish.Bilateral symmetry - horse, human
Animals in the phyla Cnidaria and Echidnodermata (for example starfish and jellyfish) have radial symmetry.
They are animals that are bilateral, they can be split into two perfectly into two, the parts that lie opposite of the axis of the worm is identical.
Radial symmetry is the main one that distinguishes cnidarians from porifera.
The hydra has radial symmetry. The hydra belongs to the phylum Cnidaria and many immobile species in this phylum exhibit radial symmetry. Some marine animals that have bilateral symmetry are fish, sea turtles, and marine mammals.
