While a longstanding method for identifying dinoflagellates, morphology alone can be inaccurate because of convergent evolution of truly different species toward a particular cellular shape. The dinoflagellate genus Togula is a case in point in that its type species Togula britannica was previously assigned to the genus Amphidinium based on morphology but was recently recognized as an independent genus following phylogenetic characterization. Chemotaxonomy can be a useful tool to complement the characterization of dinoflagellates by phylogeny.
