The jellyfish Clytia hemisphaerica is part of a group located outside of the bilaterians, cnidarians, and plays an important role in marine ecosystems. Certain polyps specialize in reproduction, budding off cltyia jellyfish.

Living sea carpet, ever spreading and budding tiny jellyfish. Het Zeepaard, 61 2: Clytia laevis Weismann, synonym. Due to their small size, embryos are suited to pharmacological approaches, to treatments with different types of molecule chemical agents, natural substances and require only small quantities. Recorded several times rafting on hemisphaeria and on their crustacean ectoparasites.

Clytia hemisphaerica (Linnaeus, 1767)

Phialidium viridicans Leuckart, basionym. Easy to raise and handle in the laboratory, all the stages of the life cycle can be cultivated and are available all year round: Campanularia minuta Nutting, synonym.

From editor or global species database. Along with ctenarians, they are the only non-bilaterian animals that have neurons and muscle cells; the medusae can swim and possesses a differentiated nervous system, striated muscles and sensory organs for balance and equilibrium.


Prev All episodes Next. But you have to look closely because Clytia measures only 5 to 20 millimeters. Commonly occurring from shallow subtidal to several tens of metres, but recorded also intertidally and down to ca m; some much deeper unchecked records.

Stomach short, quadrate, with small base; no peduncle. Clytia johnstoni Alder, synonym. Texts Christian Sardet, Sasha Bollet. Cambridge University Press, pp. Phialidium minutum Nutting, synonym. Mouth with four short lips. Oceania magnifica Mayer, possible synonym.

Clytia has proved well suited to laboratory culture and to gene function analysis during early development. Clytia hemisphaerica feeding polyps. Finally, the presence of multipotent stem cells throughout the whole life cycle of Clytia makes it a hemmisphaerica organism for the process of regeneration.

Thaumantias punctata Forbes, synonym. Linnaeus, Description Mainly after Russell, a. North-West European thecate hydroids jemisphaerica their Medusae. Anthomedusae, Leptomedusae, Limnomedusae, Trachymedusae, and Narcomedusae. Eggs and embryos can thus be easily prepared for experiments. Scientific advantages of this model organism The medusa form of Clytia is planktonic and measures roughly 1 cm in diameter.

This stage is sexual. Thaumantias hemisphhaerica Forbes, synonym. Clytia viridicans Leuckart, possible synonym.

Easy to raise and propagate, this delicate jellyfish is becoming a favorite laboratory organism for studying life cycles and gene functions. The Plymouth offshore medusa fauna.

Original Idea Christian Sardet. Clytia serrulata Bale, synonym. Clytia hemisphaerica, a member of the early-branching animal phylum Cnidaria, is emerging rapidly as an experimental model for studies in developmental biology and evolution. Campanularia attenuata Stechow, invalid junior homonym of C.


Campanularia gigantea Hincks, synonym. Depth range clytka Medusa in coastal plankton. World distribution Near- cosmopolitan in coastal waters but difficulties of identification in this genus make nearly all records suspect.

Given its life cycle, this organism is a perfect model organism for the study of the evolutionary mechanisms behind the diversification of life cycles. With a full genome sequence soon to become available, hemidphaerica a clear potential for genetic approaches, Clytia is well placed to provide invaluable information on core mechanisms in cell and developmental biology, and on the evolution of key features of animal body plans.

Beobachtungen an den Hydroiden der Kieler Bucht. Mutant strains of Clytia for genes involved in the regulation of embryogenesis are in progress. Clytia hemisphaerica Linnaeus, Clytia is an experimental research model that is particularly useful for the study of fertilisation, regeneration, ecology and physiology. Campanularia hemisphaerica Linnaeus, unaccepted combination.

Nematocysts in the Phialidium medusae of Clytia hemisphaerica Hydrozoa, Campanulariidae studied by light and scanning electron microscopy.

Campanularia gegenbauri Sars, synonym.

Campanularia edwardsi Nutting, possible synonym. Other studies are dedicated to the origin of germ cell precursors and those of the somatic cells of gonads; it is also a model for the regeneration of gonads.
