Laboratory rearing and reconstruction of Laodicea undulata (Hydrozoa) life cycle led to the discovery for the first time in Leptomedusae of the potential for ontogeny reversal, i.e. the medusa stage can asexually transform back into the polyp stage. In turn, each rejuvenated polyp stage can newly activate the standard developmental programme towards colony morphogenesis and budding of secondary medusae. These can be considered as clonemates of the initial medusa batch, since they originate by… Expand

Induction of reverse development in two marine Hydrozoans.
TLDR
It is shown here that exposure to cesium chloride (CsCl), an inducer of larval metamorphosis, may also induce RD, highlighting similarities and differences between these two master ontogenetic processes in cnidarians. Expand
“Indirect development” increases reproductive plasticity and contributes to the success of scyphozoan jellyfish in the oceans
TLDR
Evidence of a third ephyral production is provided which may be crucial for the survival of some scyphozoan populations within the frame of a bet-hedging strategy and contribute to their long evolutionary success throughout the varied conditions of past and future oceans. Expand
Ontogeny reversal and phylogenetic analysis of Turritopsis sp.5 (Cnidaria, Hydrozoa, Oceaniidae), a possible new species endemic to Xiamen, China
TLDR
It is shown, for the first time, that the two dissected parts of Turritopsis have significantly different potentials to transform into polyps, and a series of morphological changes of the reversed life cycle can be recognised. Expand
Life Cycle Reversal in Aurelia sp.1 (Cnidaria, Scyphozoa)
TLDR
This is the first evidence for back-transformation of sexually mature medusae into polyps in Aurelia sp.1, and reveals the underestimated potential of life cycle reversal in scyphozoanmedusae, with possible implications for biological and ecological studies. Expand
Towards a phylogenetic classification of Leptothecata (Cnidaria, Hydrozoa)
TLDR
A thorough taxonomic revision of the Leptothecata is offered, erecting new orders, suborders, infraorders and families and discussing the origination and diversification dynamics of the group from a macroevolutionary perspective. Expand
Reverse development in Cnidaria
TLDR
Besides their high regenerative and asexual-reproduction potential, a number of cnidarians can undergo ontogeny reversal, or reverse development: one or more stages in the life cycle can reactivate genetic programs specific to earlier stages, leading to back-transformation and morph rejuvenation. Expand
Life cycle, morphology and medusa ontogenesis of Turritopsis dohrnii (Cnidaria: Hydrozoa)
TLDR
The development of the medusa morph is reported, with description of four consecutive stages distinguished by the morphology of the umbrellar apex and the number of marginal tentacles. Expand
Mesodermal anatomies in cnidarian polyps and medusae.

  • Biology, Medicine
  • The International journal of developmental biology
  • 2006
TLDR
A hypothesis disputing the diploblast classification of cnidarians is presented without providing further explanations for the apparent diploblasty of the polyp stage and the formation of the subepidermal striated muscle in those Medusozoa lacking the entocodon nodule. Expand
The non-Siphonophoran Hydrozoa (Cnidaria) of Salento, Italy with notes on their life-cycles: an illustrated guide.
TLDR
Four species are non-indigenous, three of them with invasive behavior (Clytia hummelincki, Clytia linearis, and Eudendrium carneum), and one species now very common (EUDendrium merulum) in Salento. Expand
De Novo Assembly of the Transcriptome of Turritopsis, a Jellyfish that Repeatedly Rejuvenates
TLDR
This represents the first comprehensive set of de novo transcriptome data for this species, which may provide clues toward a better understanding of cyclical rejuvenation in multicellular animals. Expand

Motile sexual stages and evolution of Leptomedusae (Cnidaria)
TLDR
The affinities of the medusa stages between Campalecium and Eucbeilota indicate that the Haleciidae originated by the evolution of hydroids of the family Campanulinidae s.l., giving rise to the Plumulariid family. Expand
Reverse development in Cnidaria
TLDR
Besides their high regenerative and asexual-reproduction potential, a number of cnidarians can undergo ontogeny reversal, or reverse development: one or more stages in the life cycle can reactivate genetic programs specific to earlier stages, leading to back-transformation and morph rejuvenation.

Reversing the Life Cycle: Medusae Transforming into Polyps and Cell Transdifferentiation in Turritopsis nutricula (Cnidaria, Hydrozoa).
TLDR
Selective excision experiments show that the transformation of medusae into polyps occurs only if differentiated cells of the exumbrellar epidermis and part of the gastrovascular system are present, revealing a transformation potential unparalleled in the animal kingdom. Expand
Population dynamics of Eudendrium glomeratum (Cnidaria: Anthomedusae) on the Portofino Promontory (Ligurian Sea)
TLDR
The quantitative evaluation of the population shows that the situation is stable, with almost identical values at the extremes of the observed yearly time series. Expand
ON THE DEVELOPMENT AND REPRODUCTION OF THE ANTHOMEDUSAN MARGELOPSIS HAECKELI HARTLAUB
TLDR
It is to be pointed out that the hydroid is the more hardy generation, and that it endures unfavorable seasons t o produce the gonophores formed periodically in the season during which conditions for reproduction characteristic for the respective species are favorable. Expand
The cnidarian premises of metazoan evolution: From triploblasty, to coelom formation, to metamery
TLDR
The structure of the striated muscle is histologically identical to that described for triploblasts, which suggests that not all Cnidaria are diploblastic and that the subumbrellar cavity is a coelom‐like structure. Expand
Ecology of the bivalve-inhabiting hydroid Eugymnanthea inquilina in the coastal sounds of Taranto (Ionian Sea, SE Italy)
TLDR
Investigation of the life history of the bivalve-inhabiting hydroid Eugymnanthea inquilina revealed a size selection for hosts longer than 40 mm, being almost completely absent in mussels below this size, leading to reconsideration of this symbiotic association as a possible mutualism rather than a simple inquilinism.

Distinction of two morphotypes of Turritopsis nutricula medusae (Cnidaria, Hydrozoa, Anthomedusae) in Japan, with reference to their different abilities to revert to the hydroid stage and their distinct geographical distributions
TLDR
Life history studies have demonstrated rejuvenation in both morphotypes, although not as complete as the process in Mediterranean specimens, which are morphologically similar to the small type. Expand

TLDR
Older medusa buds isolated in the stages 5–8 develop normally into medusae or medusa-like structures, which means that at least part of the medusa cells has not irreversibly lost the ability to functional and structural metaplasia. Expand
