Sea cucumbers are echinoderms, a phylum that includes sea urchins and starfish.
Echinoderms have a five-way radial symmetry, a pattern most familiar in the shape of the starfish.
In sea cucumbers this character is shown in the five strips of muscle inside the body wall, running from the front to the back.
The organism was motile and bilateral in symmetry.
Bilateral symmetry means the organism can be cut right down the middle and be split into two equal halves.
The echinoderm ancestry later developed radial symmetry as it was thought to be more advantageous to the species
Step-by-step explanation:
Hope it helps you!!
