| Resumo | |
In this study, a zoantharian specimen was found associated with a gorgonian colony of the genus Nicella (Anthozoa, Octocorallia), representing the first zoantharian-octocoral association reported from the southwestern Atlantic. Unexpectedly, phylogenetic analyses of mitochondrial (COI and mt 16S rDNA) and nuclear (ITS-rDNA) markers assigned the specimen to the widely distributed species Parazoanthus cf. swiftii, known until now to associate exclusively with sponges (Porifera). In the sampled locality (Alcatrazes Archipelago, Sao Paulo State), P. cf. swiftii has been observed to associate with both sponges and octocoral. We review the literature and discuss the specificity of biotic substrate associations in Zoantharia and suggest that many interactions may not be as host-specific as previously thought. Such flexibility in habitat choice may provide the mechanisms that have allowed zoantharians to adapt and associate with a wide range of invertebrate hosts across evolutionary time scales. (AU) | |
