In modular invertebrates, the level of polymorphism may range from the production of defensive spines or reproductive structures on otherwise monomorphic zooids, to the complete partitioning of feeding, reproductive, and defensive tasks in highly polymorphic colonies such as siphonophores and some bryozoans (Reed, 1991; Harvell, 1994).
