On a pu parler des espèces présentes, leur biologie, leur écologie, les impacts humains (pêche, changement climatique...) et bien sûr de génétique! (academic.oup.com/biolinnean/a...)
Symbiosis, hybridization, and speciation in Mediterranean octocorals (Octocorallia, Eunicellidae)
Abstract. Understanding how species can form and remain isolated in the marine environment still stimulates active research. Here we study the differentiat

Here is an exemple of a scanning electronic microscopy image of a part of a black coral: the shape and ornementation of spines are important characters in the taxonomy of this group. Picture by Dero Wang at the SEM platform of @mnhn.fr

More black corals. Here is a whip like colony. With a detail on the axis.

We more specifically work on the samples from the exploration of deep sea ecosystems in New-Caledonia as for example Kanadeep 2: campagnes.flotteoceanographique.fr/campagnes/18... We hope this will lead to new collaborative work on black corals.

But the morphological criteria used in the taxonomy of these species can often be observed repeteadly in different genera or families (probably convergent evolution).

They present an important morphological diversity, for example with more or less branches or pinnules

They do not form reef, but create 3 dimensional habitats (some of which can be qualified as marine animal forests). There is a lot to learn on antipatharia, especially on deep species.

Antipatharia or black corals are a group of marine cnidaria, with a spiny proteinaceous skeleton. They can be found from 2 to 8600 m depth (depending on the species), but more than half of the known species are present below 50 m.
