Detailed explanation-1: -Most animals are bilaterally symmetrical with a line of symmetry dividing their body into left and right sides along with a “head” and “tail” in addition to a top and bottom. Only sponges (phylum Porifera) have asymmetrical body plans.
Detailed explanation-2: -Importantly, she notes, not all animals are bilaterally symmetrical. Some animals have radial symmetry with four or five axes, like starfish, jellyfish and sea urchins. The only creature on Earth who is not symmetrical in any way is the sponge.
