Chemical and physical defenses of Singapore gorgonians (Octocorallia: Gorgonacea)

Journal of Experimental Marine Biology and Ecology, 2000
Gorgonians are abundant in tropical waters and their polyps are seldom predated on. This study investigates how gorgonians defend themselves chemically and physically against fish predation. Gorgonian extracts and sclerites were incorporated into fish feed and tested on reef fishes. Laboratory bioassays using Greyhead wrasses, Halichoeres purpurescens,

The pennatulacean genus Cavernularia Valenciennes (Octocorallia: Veretillidae)

Zoological Journal of the Linnean Society, 1989
Two new species of sea pens referable to the genus Cavernularia Valenciennes are described from Natal and Transkei, east coast of southern Africa, at depths of 24 and 190 to over 300 m. The two new species are distinguished from other members of the genus by unique combinations of features regarding the axis, colonial growth form, autozooid size, as ...

Notes on Alcyonacea (Octocorallia) from Tanzania

1992
For the first time Alcyonacea from Tanzania are recorded, including two new species: Cladiella daphnae and Sinularia platylobata. Both these species are described and figured, while descriptions are also given of specimens of Lobophytum crassum von Marenzeller, 1886, L. rotundum Tixier-Durivault, 1957, and L. venustum, Tixier-Durivault, 1957.

Hydromechanical Adaptations in Alcyonium Sidereum (Octocorallia)

1980
The relation between colony size and shape vs. flow regime was investigated in a boreal species of octocoral, Alcyonium sidereum with particular regard to two hydrodynamic problems faced by these organisms: (1) maximizing the area of feeding surfaces presented to flow while (2) limiting potentially damaging drag forces induced by water movement.

Antimicrobial activity in gorgonian corals (Coelenterata, Octocorallia)

Coral Reefs, 1994
Coral surfaces are often colonized by bacteria and other microbes that may be pathogenic as well as surface-fouling. To test the hypothesis that corals possess antimicrobial properties, both polar and non-polar extracts from eight species of gorgonian corals were assayed against five species of bacteria.

The Melithaeidae (Coelenterata: Octocorallia) of Singapore

2000
Four species of Melithaeidae from Singapore waters are described and depicted: Melithaea ochracea (Linnaeus, 1758), Mopsella rubeola (Wright & Studer, 1889), M. retifera (Lamarck, 1816), and Acabaria robusta (Shann, 1912). Variation and synonymy are discussed.
