    1. a hard stony substance secreted by certain marine coelenterates as an external skeleton, typically forming large reefs in warm seas:
      "a coral reef" · "the nearby coral islands, lagoons, and atolls"
    2. a sedentary coelenterate of warm and tropical seas, with a calcareous, horny, or soft skeleton. Most corals are colonial and many rely on the presence of green algae in their tissues to obtain energy from sunlight.
    3. the unfertilized roe of a lobster or scallop, which is used as food and becomes reddish when cooked:
      "we had scallops with their coral, in their fluted shells"

    Does Hexacorallia have bioluminescence?
    Bioluminescence is not as prevalent in Hexacorallia, which may have evolved a different genetic basis for light emission. Among hexacorals, bioluminescence is primarily maintained in the early-diverging order Zoantharia, which lacks skeletons—the predicted ancestral skeletal state of Anthozoa [ 10 ].

    Are Octocorallia paraphyletic?
    Octocorallia includes blue coral and soft corals and species of Octocorallia have polyps with an eightfold symmetry, each polyp having eight tentacles and eight mesenteries. The group of corals is paraphyletic because the sea anemones are also in the sub-class Hexacorallia.

    When did bioluminescence occur in Hexacorallia?
    Among Anthozoa, bioluminescence is found in both major classes that diverged approximately 770 million years ago (Ma). For Hexacorallia, according to current observations, bioluminescence was only retained in the early-diverging orders Zoantharia and Actiniaria ( figure 1, crown ages 430–515 Ma).

    Where did Octocorallia come from?
    Our divergence dating placed the origin of Octocorallia approximately 542 Ma ( figure 3 ), whereas Quattrini et al. [ 10] estimated the origin of Octocorallia in the Ediacaran (575 Ma, 95% CI: 484–685 Ma, figure 1 ).
