Pentamerism
In biology, pentamerism, also known as pentaradial symmetry, is a unique body symmetry exhibited primarily by starfish. It is rotational symmetry with respect to an angle of 72°, i.e. somewhat like radial symmetry, but less than that, with the body arranged around the axis of the mouth with five equal sectors.
