Шаблон:Short description Шаблон:Speciesbox

Antillogorgia bipinnata, the bipinnate sea plume, is a species of colonial soft coral, a sea fan in the family Gorgoniidae. It is found in the Caribbean Sea. It was first described as Pseudopterogorgia bipinnata in 1864 by the American zoologist Addison Emery Verrill. Williams and Chen (2012), transferred all the Atlantic species of Pseudopterogorgia to Antillogorgia.[1]

Description

Antillogorgia bipinnata is a colonial soft coral growing in the form of a bipinnate fan usually in a single plane. It can grow to a height of about Шаблон:Convert with a slightly smaller width. It consists of a main stem with several branches, with regularly-spaced pairs of branchlets. The branchlets are stiff, slightly flattened, and typically Шаблон:Convert long and Шаблон:Convert in diameter. They are spaced about Шаблон:Convert apart and project at an angle of about 65° from the branch. The apertures from which the polyps protrude are small and slit-like and are arranged in staggered double rows on either side of the branchlets. The colour of this sea fan is usually violet or purple but may be yellow or whitish.[2][1]

Distribution and habitat

Antillogorgia bipinnata is found in shallow water reefs in the Bahamas, South Florida and the Caribbean Sea. It usually grows in the depth range Шаблон:Convert but can grow as deep as Шаблон:Convert.[1]

Biology

Mature specimens of Antillogorgia bipinnata have symbiotic unicellular algae known as zooxanthellae in their tissues, but these are not present in the planula larvae and the polyp into which it metamorphosizes. Researchers reared these larvae in algae-free environments and then attempted to infect the resulting polyps with various strains of dinoflagellate. Some of these were observed to be attracted to the polyps and actively swam into their open mouths; successful infection was achieved with some strains of dinoflagellate and not with others.[3]

Secondary metabolites

Several secondary metabolites have been isolated from Antillogorgia bipinnata including the cytotoxic cembranoids denoted bipinnatin A to D,[4] and the diterpene bipinnatin J.[5]
