The bilaterally symmetrical larvae which transform into radially symmetrical adult is

The most common larva is a bipinnaria larva which is bilateral symmetrical and when it becomes adult, it transforms itself into radially symmetrical.

Note: In radial symmetry:

i. The body parts are arranged around the central axis.

ii. If we cut through the central axis in any direction, it can be divided into similar halves.

iii. E.g. Hydra, jelly fish and star fish.

In bilateral symmetry:

i. The body parts are arranged along a central axis.

ii. If we cut through the central axis, we get two identical halves.

iii. E.g. Frog.
