How is a starfish body more complicated than a sponge?
The body of a starfish (phylum:echinoderm) has nerves and tissues, while a sponge (porifera) does not. Sponges do not have any appendages, hence they are not motile. Neither sea stars nor sponges have a brain, and the sea stars nervous system is quite simple. Sea stars also have digestive organs, tube feet, and sesory cells that can detect light, gravity, and chemicals. Sponges do not. Thus, Porifera is the lowest phylum in the kingdom of Animalia.
