Шаблон:Short description Шаблон:Automatic taxobox

Aequoreidae is a family of hydrozoans, sometimes called the many-ribbed jellies or many-ribbed jellyfish.[1][2] There are approximately 30 known species found in temperate and tropical marine coastal environments.[3] Aequoreids include Aequorea victoria, the organism from which the green fluorescent protein gene was isolated.[4]

Polyps

Only the polyp stages of Aequorea species have been observed.[5] The colonies are covered with chitinous periderm and can be either prostrate or erect with weak or sympodial branching.[5] Young Шаблон:Abbr possess [[Hydrotheca|Шаблон:Abbr]] with a closing structure called operculum,[5] which consists of several relatively long triangular folds that meet together in the centre when a disturbed polyp contracts.[5] Because the operculum is quite fragile, hydrothecae of old polyps usually have only a small chitinous collar remaining.[5] Comparatively large cylindrical Шаблон:Abbr are attached to the colony with a thin peduncle.[5] Commonly only one medusa develops in each gonotheca.[5]

Medusae

Mature aequoreid medusae are diverse in shape, from lens-like to conical, and in size.[3] The smallest, Aequerea parva is only 0.6 cm in diameter, while the largest, Rhacostoma atlanticum, can reach 40 cm in diameter.[3][5] The medusae of most species are between 5 and 15 cm in diameter.[3]

Genera
