- It is not known whether rugose corals had symbiotic photosymbiotic zooxanthellae as modern corals do.
- Both coral and sponge were sparse, and the former largely without color - giving symbiotic zooxanthellae.
- These zooxanthellae may be found in many marine invertebrates, including sponges, corals, jellyfish, and flatworms, as well as within protists, such as ciliates, foraminiferans, and colonial radiolarians.

Example sentencesExamples - A total of 41 species of zooxanthellate corals were recovered from the unit, including 21 new records.
- Based on corallite configuration, growth form and analogy with Acropora, Blastozopsammia had a relatively high degree of colony integration and may have been zooxanthellate.
