Description: Single cells of the coccoid phase spherical to broadly ellipsoidal. Mean coccoid cell sizes range from 9 to 11 ?m. Thecate motile cells lack EAV (=acrobase) suture (Figure 2C). Nucleus contains ~ 74 condensed chromosomes. Genome size is largest (~ 5 GB) relative to other Symbiodiniaceae and appears to have undergone a duplication event prior to the radiation of this genus. Genome contains the highest number of gene families in the Symbiodiniaceae. Associates with a broad range of hosts, including corals and other cnidarians, clams, ciliates, flatworms, foraminifera, and sponges. Physiologically diverse, adapted to a wide range of temperatures and irradiance levels. Most are host-specialized, but some are ecologically abundant host-generalists. Dinoflagellates whose partial sequences of LSU rDNA (containing the variable domains D1/D2) vary in nucleotide differences by no more than 5% from that of type species C. goreaui [FJ529545] are defined as members of this genus.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
