Abstract
Currently considered an excellent candidate source of novel chemical diversity, the existence of marine myxobacteria was in question less than 20 years ago. This review aims to serve as a roll call for marine myxobacteria and to summarize their unique features when compared to better-known terrestrial myxobacteria. Characteristics for discrimination between obligate halophilic, marine myxobacteria and halotolerant, terrestrial myxobacteria are discussed. The review concludes by highlighting the need for continued discovery and exploration of marine myxobacteria as producers of novel natural products.
