WikiMatrix Historically, the "Ceriantipatharia" was thought to be a separate subclass but, of the two orders it comprised, Antipatharia is now considered part ...Antipatharians, commonly known as black corals, represent a taxonomic order within the anthozoan subclass Hexacorallia that encompasses 7 families, 43 genera and over 235 species (see Daly et al., 2007; Bo 2008). Black corals have long been treasured by humans for a variety of purposes ranging from jewellery to their presumed ability to fend ...

Montipora aequituberculata. Montipora aequituberculata is native to the Indo-Pacific region. Its range extends from the Red Sea and Gulf of Aden, through the Indian Ocean to Japan, the East China Sea, Australia and the west and central Pacific. It is found on the upper parts of reef slopes where it may be the most predominant species.Among octocorals, colonies of the deep-sea pennatulacean genus Umbellula Gray, 1870 are some of the most instantly recognisable forms. Historically however, species identification in this genus ...The marginal musculature of Hexacorallia (also known as the marginal sphincter or Rotteken’s muscle of Actiniaria) arises through hypertrophy of columnar circular muscles at the margin of the polyp [19, 23, 24]. The columnar circular muscles, which line the length of the column, are often anchored to miniscule mesogleal pleats (increasing ...A remarkable insight into 600 marine species described between 2017-2021.

In the Hexacorallia clade, they are basal to the scleractinians, being more derived than sea anemones and the Zoantharia (Brugler and France 2007; Sinniger and Pawlowski 2009). Recent estimates suggest that the first split of lineages within the scleractinian hexacorals took place approximately 425 million years ago (Stolarski et al. 2011 ...Jun 18, 2019 · Research on so-called “minor taxa” at mesophotic depths has lagged behind that of more commonly researched groups such as fish or hard corals. Exemplar taxa include species of the order Zoantharia, benthic colonial anemones that are cosmopolitan in distribution but understudied in many ecoregion and ecosystems. In this study, we …

It includes all the stony corals, most of which are colonial and reef -forming. It also contains the sea anemones, tube anemones, and zoanthids, in six living orders. Hexactinellida.
