Open AccessMedusozoan genomes inform the evolution of the jellyfish body plan
Cnidarians are astonishingly diverse in body form and lifestyle, including the presence of a jellyfish stage in medusozoans and its absence in anthozoans. Here, we sequence the genomes of Aurelia aurita (a scypho...

Open AccessA secreted antibacterial neuropeptide shapes the microbiome of Hydra
Colonization of body epithelial surfaces with a highly specific microbial community is a fundamental feature of all animals, yet the underlying mechanisms by which these communities are selected and maintained...

Naturally occurring tumours in the basal metazoan Hydra
The molecular nature of tumours is well studied in vertebrates, although their evolutionary origin remains unknown. In particular, there is no evidence for naturally occurring tumours in pre-bilaterian animals...

Chapter
Hydra Go Bacterial
This chapter provides an overview of how the basal metazoan Hydra serves as model for untangling and dissecting the fundamental principles underlying complex host–microbe interactions.

Sympagohydra tuuli (Cnidaria, Hydrozoa): first report from sea ice of the central Arctic Ocean and insights into histology, reproduction and locomotion
Various cnidarians have adapted their life style to interstitial habitats of marine sediments. Recently, for the first time a hydroid was reported from the interstitial brine channel system of Arctic fast ice....

Open AccessCharacterization of taxonomically restricted genes in a phylum-restricted cell type
Despite decades of research, the molecular mechanisms responsible for the evolution of morphological diversity remain poorly understood. While current models assume that species-specific morphologies are gover...

‘Candidatus Hepatincola porcellionum’ gen. nov., sp. nov., a new, stalk-forming lineage of Rickettsiales colonizing the midgut glands of a terrestrial isopod
The midgut glands (hepatopancreas) of terrestrial isopods are densely colonized by hitherto uncultivated bacteria. In the case of the Common Woodlouse, Porcellio scaber (Crustacea: Isopoda), the symbionts represe...

Expression of developmental genes during early embryogenesis of Hydra
Hydra is a classical model to study key features of embryogenesis such as axial patterning and stem cell differentiation. In contrast to other organisms where these mechanisms are active only during embryonic de...

Functional morphology of the ommatidia in the compound eye of the moth, Antheraea polyphemus (Insecta, Saturniidae)
The fine structure of the superposition eye of the Saturniid moth Antheraea polyphemus Cramer was investigated by electron microscopy. Each of the approximately 10000 ommatidia consists of the same structural com...

Identification and localization of visual pigments in the retina of the moth, Antheraea polyphemus (Insecta, Saturniidae)
In the compound eye of the moth Antheraea polyphemus, three types of visual pigments were found in extracts from the retina and by microspectrophotometry in situ. The absorption maxima of the receptor pigment P a...

Investigations on the cuticle of the polychaete elytra using energy dispersive X-ray analysis
Energy dispersive X-ray analysis of elements with Z>11 in a SEM (scanning electron microscope) was used to investigate the elytra ofLagisca extenuata, Lepidonotus clava, andHarmothoe areolata from Naples (Italy) ...
