Radial Symmetry
Larvae show bilateral and adult sea urchin show penta-radial symmetry .
radial symmetry
Because most sea cucumbers crawl along the sea floor, the top surface is slightly different from the bottom one that is constantly pressed against the sea floor. Thus, there is a weak transverse bilateral symmetry.
they have what we call "pentaradial" symmetry, but certain species, such as the sand dollar, and the sea cucumber, have a secondary body symmetry, which is a bilateral symmetry
