Abstract
This article reviews existing literature on the known. Chrysochromulina species, and describes work that has been conducted on the life cycle and taxonomic affinities of these nanoplanktonic protists. In light of this information, we propose functions for the scales, muciferous bodies, and haptonema, and their relationship to toxicity, presenting a theory of auxotrophy following induced osmosis (''dasmatrophy'') by cooperative assemblages of Chrysochromulina species. Dasmotrophy (from Greek .delta..alpha..sigma..mu.o.sigma., taxation) is a form of remote parasitism. Prey organisms are compelled to return a small fraction of their contained nutrients to the environment through transient leaks in cell membranes caused by extracellular chemicals produced by Chrysochromulina. Successful dasmotrophy requires corresponding behaviour on the part of the organism, expressed as a characteristic life style and well exemplified by Chrysochromulina.
