    Noms communs: colonial-cup coral (English), orange-cup coral (English), orange-tube coral (English), tubastrée orange (French)
    Type d'organisme: corail
    Tubastraea coccinea a été introduite dans tous les continents, sauf l'Antarctique, et elle est susceptible d'entrer en compétition pour l'espace avec des invertébrés benthiques et menace leurs populations. La diminution des éponges et des coraux indigènes pourrait aussi avoir d'importants effets sur le fonctionnement d'écosystèmes entiers.
    Description
    Tubastraea coccinea (orange-cup coral) are non-reef building coral species that extend beautiful translucent tentacles at night (Hawaii Coral Reef Network 2005). The orange cup coral is a heterotroph (consumer) that does not contain zooxanthellae (endosymbiotic dinoflagellates or algae) as most corals do (Blomquist et al. 2006).

    Description de l'habitat
    Tubastraea coccinea (orange-cup coral) inhabit shaded vertical surfaces and caverns down to huge depths. Orange-cup-corals are also found in very cold water throughout the world (Hawaii Coral Reef Network 2005). Orange-cup corals often dominate tropical habitats not occupied by other coral species, such as wrecks and cryptic reef habitats (Vermeij 2006). They also colonise artificial structures (Fenner and Banks 2004, Sammarco et al. 2004) but experiments have demonstrated similar preferences for granite, cement, steel and tile (Creed & De Paula 2007). In Brazil they are most abundant in the shallow sub-tidal zone at shallow depths between 0m and 3m (De Paula & Creed, 2004, 2005, Creed 2006).
    Impacts globaux
    Although Tubastraea coccinea (orange-cup coral) is listed on the Convention on International Trade in Endangered Species website and database (see Tubastraea coccinea in CITES species Database) it often competes with other benthic invertebrates for substratum space (Vermeij 2006). This may put native species at risk, particularly sponges and native corals. Local exclusion or extinction of such species may occur and the removal of the native corals may reduce the production of the entire ecosystem, compromising ecosystem functions (Creed 2006).
    Distribution géographique
    Native range: Tubastraea coccinea (orange-cup coral) is native to the Indo-Pacific region (Fenner and Banks 2004).
    Known introduced range: Caribbean (Fenner and Banks 2004), Asia, Africa, Australasia, Pacific, North America, Central America and South America.
    Informations pour la gestion de l'espèce
    Manual: In Brazil a control and eradication programme called “Projeto Coral-Sol” is removing Tubastraea coccinea from the environment (Joel Creed, pers.comm., 2007).
    Alimentation
    Cup-coral species rely upon capturing zooplankton as food (Hawaii Coral Reef Network 2005).
    Reproduction
    Tubastraea coccinea is hermaphroditic and produces planulae (flat, free-swimming, ciliated larva) asexually (ameiotically) (Ayre and Resing 1986). Gonads are unlikely to be involved in the asexual production of brooded larvae (Ayre and Resing 1986). It is able to form “runners” (a thin tissue outgrowth lacking polyps) which extend at a growth rate of up to 10.4cm per year until they encounter unoccupied patches of substratum. New polyps then form at the end of the runners (Vermeij 2005).
    Stades du cycle de vie
    The reproductive age of the Tubastraea coccinea is around 1.5 years and growth averages at approximately 3cm² per year (Vermeij 2006). It increases in local abundance by reaching maturity at a small size and producing planula at an early age (Vaughan 1919; Van Moorsel 1989; Fenner and Banks 2004, in Vermeij 2006).
