The next Phylum
The Phylum Priapulida ( Phallus worms )
Characteristics
of this phylum include, bilaterally symmetrical. It's body has more than two cell layers, tissues and organs. Body cavity
is a coelom. Has no circulatory system. Reproduces sexually, and lives in marine environments
We can see a relationship here because all three phylum possess, more or less, the same characteristics
in terms of reproduction, apperance, habitat, and feeding. There is a close connection between each phylum to the pylum Mollusca,
because the pylum Mollusca is in between them.
