The dinoflagellate lineage Syndiniales currently consists entirely of parasitic species that fall into five well-supported clades. Environmental sequencing studies worldwide have found an abundance of Syndiniales in a variety of marine ecosystems, but very little is known about the majority of Syndiniales species including two entire clades which have only been observed in sequence data. Syndiniales are known to have a wide range of ... actual infections. Here, we describe the diversity of Syndiniales found at the Scripps Institution of Oceanography pier ...
