Revisão taxonômica do gênero Thesea (Cnidaria: Octocorallia) do Atlântico Ocidental
The study of genus Thesea Duchassaing & Michelotti, 1864, was done by the examination of type material of its species. The name Thesea presents nomenclatural problems concerning the designation of type species. An identification key, illustrations, and diagnosis of validated species are given. The …

Revisão sistemática dos Octocorallia (Coelenterata, Anthozoa) dos recifes de Abrolhos, BA, Brasil
… studies were developed on shallow water Octocorallia (Coelenterata, Anthozoa) from the Abrolhos area, Bahia, Brazil. These studies were based on material from collections in Brazilian and American institutions. The specimens from Abrolhos were compared with specimens of other localities …

Octocorallia (Cnidaria: Anthozoa) da plataforma continental e ilhas oceânicas brasileiras: famílias Paramuriceidae e Plexauridae
Fourteen species of octocorals, from the Brazilian continental platform and oceanic islands, from depths between 20 and 400m, were studied regarding aspects of their taxonomy, bathymetry, and geographical distribution. These species included nine Paramuriceidae (Bebryce cinerea, Bebryce sp., …

Phylogenetics, systematics and biogeography of deep-sea Pennatulacea (Anthozoa: Octocorallia): evidence from molecules and morphology
… age and phylogeny. Pennatulids (Anthozoa:<br/>Octocorallia) are a group whose taxonomy and phylogenetic relationships remain poorly<br/>known and little studied, in spite of their abundance and ecological importance in softbottom<br/>communities. Phylogenetic analysis of a combination of …

Part 1. Biologically Active Compounds From Agelas Sponges. Part 2. Barnacle Settlement Inhibitors From Octocorallia (Antifouling, Antibacterial, Renillafoulins, Antiviral, Caribbean)
Biologically active extracts of the Caribbean sponges Agelas coniferin and Agelas cf. mauritiana have been found to contain seven new bromopyrroles (1a, 3a-8a), as well as the known debromooroidin-dimer sceptrin (2a). These compounds, isolated as the diacetate salts, were found to be antibacterial …

Evolutionary patterns within the Anthozoa (phylum Cindaria) reflected in ribosomal gene sequences
… and at the ordinal level within the Subclass Octocorallia. Traditional cladistics using morphological data have resulted in disagreements over taxonomic relationships, primarily due to a paucity of morphological characters within the Anthozoa and ambiguity about the significance of any given …

Development of proxy seawater records from gorgonian coral skeletons
… potential of gorgonian corals (Cnidaria: Octocorallia) as archives of past oceanic conditions is less well explored. Gorgonians are widely distributed throughout the world’s oceans from the shallows to great depths, and with banded skeletons formed of organic gorgonin and calcite, the …
