Siphonophores are free-swimming colonial hydrozoans (Cnidaria) composed of asexually produced multicellular zooids. [...] Key Result Each bud gives rise to a precise, directionally asymmetric sequence of zooids through a stereotypical series of subdivisions, rather than to a single zooid as in most other hydrozoans. This initial description of development in a deep-sea siphonophore provides an example of how precise colony-level organization can arise, and illustrates that the morphological complexity of…Expand
The evolution of colony-level development in the Siphonophora (Cnidaria:Hydrozoa)
TLDR
It is shown that gonodendra and gastrozooids of the examined cystonects arise as independent buds directly on the stem, whereas probud subdivision is a synapomorphy of the Codonophora, and symmetry is labile in siphonophores, with multiple gains and/or losses of directional asymmetry in the group.

Molecular phylogenetics of the siphonophora (Cnidaria), with implications for the evolution of functional specialization.
TLDR
Maximum likelihood and Bayesian analyses of morphological data suggest that the transition rate for decreased functional specialization is greater than the Transition rate for increased functional specialization for three out of the four investigated categories of polyps and medusae. Expand
Re-evaluation of characters in Apolemiidae (Siphonophora), with description of two new species from Monterey Bay, California.
TLDR
The observations presented here greatly clarify the interpretation of diagnostic characters within Apolemiidae, bear on the status of the three previously described species, provide critical detail for understanding the diversity of colony-level organization in siphonophores, and establish a foundation for the description of additional apolemiid species. Expand
Stem cells in a colonial animal with localized growth zones
TLDR
This work characterize the distribution of interstitial stem cells (i-cells) in the siphonophore Nanomia bijuga and finds that i-cells are present at the tips of the growth zones, at well-defined sites where new zooids will arise, and in the youngest zooid buds. Expand
Cnidarian phylogenetic relationships as revealed by mitogenomics
TLDR
These analyses suggest that the shared morphological characters in these groups are plesiomorphies, originated in the branch leading to Medusozoa, and the hypothesis that Staurozoa is the sister group to all the other medusozoans is rejected. Expand
Genetic identity of two physonect siphonophores from Southern Ocean waters – the enigmatic taxon Mica micula and Pyrostephos vanhoeffeni
TLDR
In the present study 34 nectophores of P. vanhoeffeni and four colonies of M. micula collected from three areas in the Southern Ocean were analysed for the 16S rRNA gene, and five haplotypes were identified, which formed two clearly distinct lineages. Expand
Improved phylogenetic resolution within Siphonophora (Cnidaria) with implications for trait evolution
TLDR
This new phylogeny is used to reconstruct several traits that are central to siphonophore biology, including sexual system, gain and loss of zooid types, life history traits, and habitat, and find strong support for new clades within Codonophora that were previously unresolved. Expand
Morphology and development of the Portuguese man of war, Physalia physalis
TLDR
This work proposes a framework for homologizing the axes with other siphonophores, and suggests that the tentacle bearing zooids should be called tentacular palpons, and looks at live and fixed larval and non-reproductively mature juvenile specimens and uses optical projection tomography to build on existing knowledge about the morphology and development of this species. Expand
Evolution of gene expression across species and specialized zooids in Siphonophora
TLDR
Gen expression patterns tended to be largely consistent in zooids with the same function across species, but also some large lineage-specific shifts in gene expression, which shows that patterns of gene expression have the potential to define zooids in colonial organisms. Expand
Stem cells in Nanomia bijuga (Siphonophora), a colonial animal with localized growth zones
TLDR
The first evidence for i-cells in a siphonophore is provided, and maintenance of i-cell populations at the sites of growth zones are suggested and may explain the reduced developmental plasticity in older parts of the colony. Expand

Embryonic versus blastogenetic development in the compound ascidian Botryllus schlosseri: Insights from Pitx expression patterns
TLDR
Full‐length cDNA cloning of a B. schlosseri Pitx ortholog (Bs‐Pitx) and expression analysis during both embryo/metamorphosis and blastogenesis provide the first evidence for a key developmental gene being deployed in essentially similar ways in two different developmental sequences that eventually give rise to similar zooids.

Experimental heterochrony in hydractiniid hydroids: Why mechanisms matter
TLDR
Experimental studies of two hydractiniid species show that both morphological and life history heterochronies correlate with patterns of gastrovascular circulation, however, similar experimental perturbations of energy metabolism have opposite heterochronic effects on the two species. Expand
Investigating the origins of triploblasty: `mesodermal' gene expression in a diploblastic animal, the sea anemone Nematostella vectensis (phylum, Cnidaria; class, Anthozoa)
TLDR
The developmental expression of seven genes from Nematostella are studied, and the predominantly endodermal expression of these genes reinforces the hypothesis that the mesoderm and endoderm of triploblastic animals could be derived from the endoderman of a diploblastics ancestor. Expand
Variations on a theme? Polyp and medusa development in Podocoryna carnea
The life cycles of many cnidarian species are notable for including two stages with very different morphologies – sessile polyp and swimming medusa. Cnidarians thus provide an opportunity to studyExpand
Conservation of Brachyury, Mef2, and Snail in the myogenic lineage of jellyfish: a connection to the mesoderm of bilateria.
TLDR
It is concluded that the common ancestor of the cnidarians and bilaterians not only shared genes that play a role in regulating myogenesis but already used them to develop and differentiate muscle systems similar to those of triploblasts. Expand

A golden age of gelata: past and future research on planktonic ctenophores and cnidarians
TLDR
The study of the natural history of gelatinous zooplankton (‘gelata’) reached a high point at the end of the 19th century, when scientists first began to understand the phylogenetic and ecological links between cnidarians and ctenophores, and now has the opportunity to bring gelata back into primacy.

EST Analysis of the Cnidarian Acropora millepora Reveals Extensive Gene Loss and Rapid Sequence Divergence in the Model Invertebrates
TLDR
Gene loss has been much more extensive in the model invertebrate lineages than previously assumed and, as a consequence, some genes formerly thought to be vertebrate inventions must have been present in the common metazoan ancestor. Expand
