[biology] A grex (or slug) is a multicellular aggregate of amoeba of the groups Acrasiomycota or Dictyosteliida that can be formed when the amoeba run out of food. It takes its form when the column formed from the aggregation of cells collapses due to its height, and becomes a slug-shaped mass. The grex moves as a unit, and the individual o...
