WebFeb 9, 2024 · The facultatively symbiotic northern star coral, Astrangia poculata, naturally occurs as both symbiotic and aposymbiotic (lacking algal symbionts) polyps – sometimes on the same coral colony. Thus, it is possible to separate the heat stress response of the coral host alone from the coral in symbiosis with its symbiont Breviolum psygmophilum. Astrangia is a genus of stony corals in the family Rhizangiidae. Members of this genus are non-reef building corals and are found in the Atlantic and Indo-Pacific Oceans.
