During the feeding phase of the cellular slime mold, the organism exists as an amoeba-like body of that feed on organic material, bacteria, and fungus. If food becomes scarce, some of the cells of the slime mold emit a that other slime mold cells react to and they gather into a larger, single slimy mass. This is the slug phase because the mass looks and acts much like a slug. From the slug phase, will evolve and individual spores are released that are capable of becoming new individual amoeba-like cells, and they enter the feeding phase.
