Animals that have their body parts arranged around a central point are radially symmetrical.
In the field of biology, symmetry refers to the arrangement of the body and its parts with respect to an axis, a center or a plane.
In this sense, we speak of radial symmetry when a heteropolar type axis is contemplated (that is, it is different at its ends).
Radial symmetry, therefore, divides the body into:
Among the animals that have radial symmetry of different kinds, it is possible to find echinoderms, anemones and sponges.
Animals with some type of radial symmetry usually have sensory receptors that are distributed evenly throughout the body periphery.
Therefore, we can conclude that animals that have their body parts arranged around a central point are radially symmetrical.
