An animal has RADIAL symmetry when its body is organized around a center, ASYMMETRY when its body lacks symmetry, and BILATERAL symmetry when its body has distinct left and right halves.
What is animal body symmetry?
Animal body symmetry refers to an evolutionary characteristic that is used to classify major groups of animals.
Radial symmetry (e.g., echinoderms) is when the body is organized around a center.
Conversely, animals with bilateral symmetry (e.g., insects, spiders, vertebrates) have a body organized into two roughly equal left and right halves.
In conclusion, an animal has RADIAL symmetry when its body is organized around a center, ASYMMETRY when its body lacks symmetry, and BILATERAL symmetry when its body has distinct left and right halves.
