Solution:

In biradial symmetry, the body can be divided into two similar halves by one or two vertical planes only, eg, sea anemones. The animals which show radial and biradial symmetry have oral and aboral sides. The oral side has mouth, whereas the aboral side is one which is opposite to oral side.
