“…This result shows that the thermal plasticity depends on population origin and that Mediterranean populations of L. peploides are likely to have a competitive advantage in warming conditions. Greater plasticity in habitat and substrate choice was also observed in an invasive as compared to a native population of the brittle star Ophiothela mirabilis Verrill, 1867 (Tavares et al, 2021), whereas another study demonstrated a rapidly expanding fundamental niche in a freshwater dinoflagellate, Ceratium furcoides (Levander) Langhans 1925, which enables it to colonize areas outside its original climatic range (Macêdo et al, 2021). However, particular types of phenotypic plasticity, dispersal, growth and tolerance traits are difficult to generalize across AIS, e.g., even within high-impact invasive aquatic plants, these traits depended on plant growth form (Hussner et al, 2021).…”

“…Although the corals and brittle star have evolved very different life histories, like Tubastraea spp., O. mirabilis possesses several traits that allow for rapid colonization of new habitats in western Atlantic warm waters. Sun corals are sessile, epibenthic species with major impacts on benthic communities (Lages et al 2011;Sammarco et al, 2015;Luz et al, 2017;Guilham et al, 2020) whereas individuals of O. mirabilis are vagile, highly active epizoites usually associated with diverse benthic taxa, especially cnidarians and sponges (Mantelatto et al 2016; Fortunato and Lôbo-Hajdu 2021; Tavares et al 2021). While both Tubastraea spp.…”

Widespread and large populations of the exotic eastern Pacific ophiuroid brittle star Opthiothela mirabilis now occur in southeastern Florida, extending the range of this recently introduced species from southern Brazil northward to the eastern Caribbean Sea and Florida. The Florida brittle stars, representing two lineages, are epibionts on shallow (3-18 m depth), tropical/subtropical plexaurid (e.g., Eunicea spp., Muricea elongata) and gorgoniid (Antillogorgia spp.) octocorals. The scope of this study includes recent distributional records of O. mirabilis in south Florida, field abundances in relation to the cohabiting endemic ctenophore Coeloplana waltoni, behavioral observations of the ophiuroid, ctenophore and the predatory amphipod Caprella penantis, as well as a laboratory experiment testing the effects of the alien ophiuroid on the native ctenophore. Individuals of O. mirabilis have been collected near St. Lucie Inlet, extending its northern-most range by about 110 km since 2019. Two years of field sampling have demonstrated significant declines of the native, benthic ctenophore with increasing abundances of the exotic ophiuroid. Evidence suggests that the ophiuroid is negatively affecting the abundances of the ctenophore through interference competition, greatly aided by its abrasive armature of calcareous spines, plates and hooks. Sporadic and intense predation by a caprellid amphipod (Caprella penantis) also probably contributes to the ctenophore’s decline, but to a lesser extent than that caused by the ophiuroid. Adding to the risk of extinction of C. waltoni is its narrow requirement of living octocorals as hosts and restricted distribution in southeast Florida and the Bahamas.

“…In just 20 years, individuals of O. mirabilis have colonized coastlines spanning more than 6000 km of latitude (Tavares et al 2021), from their first reported presence in southern Brazil (Hendler et al 2012) northward along the South American coast to the Caribbean Sea (Hendler and Brugneaux 2013;Ferry et al 2020) and southeastern Florida (Glynn et al 2019). Their northern-most occurrence on the Florida east coast, observed on 28 September 2019, was at Deerfield Beach, 26.3184°N, 80.0998°W (Glynn et al 2020).…”

Widespread and large populations of the non-native eastern Pacific ophiuroid brittle star Ophiothela mirabilis now occur in southeastern Florida, extending the range of this recently introduced species from southern Brazil northward to the eastern Caribbean Sea and Florida. The Florida brittle stars, representing two lineages, are epibionts on shallow (3-18 m depth), tropical/subtropical plexaurid (e.g., Eunicea spp., Muricea spp.) and gorgoniid (Antillogorgia spp.) octocorals. The scope of this study includes recent distributional records of O. mirabilis in south Florida, field abundances in relation to the cohabiting endemic ctenophore Coeloplana waltoni, behavioral observations of the ophiuroid, ctenophore and the predatory amphipod Caprella penantis, as well as a laboratory experiment testing the effects of the non-native ophiuroid on the native ctenophore. Individuals of O. mirabilis have been collected near St. Lucie Inlet, extending its northern-most range by about 110 km since 2019. Two years of field sampling have demonstrated significant declines of the native, benthic ctenophore with increasing abundances of the non-native ophiuroid. Evidence suggests that the ophiuroid is negatively affecting the abundances of the ctenophore through interference competition, greatly aided by its abrasive armature of calcareous spines, plates and hooks. This detrimental effect justifies considering O. mirabilis as an invasive species in south Florida. Sporadic and intense predation by a caprellid amphipod also probably contributes to the ctenophore's decline, but to a lesser extent than that caused by the ophiuroid. Adding to the risk of extinction of C. waltoni is its narrow requirement of living octocorals as hosts and restricted distribution in southeast Florida and the Bahamas.
