The ability to perform muscle contractions is one of the most important and distinctive
features of eumetazoans. As the sister group to bilaterians, cnidarians (sea anemones …

How do animals regenerate specialised tissues or their entire body after a traumatic injury,
how has this ability evolved and what are the genetic and cellular components underpinning …

We present an organism-wide, transcriptomic cell atlas of the hydrozoan medusa Clytia
hemisphaerica and describe how its component cell types respond to perturbation. Using …

Jellyfish (medusae) are a distinctive life-cycle stage of medusozoan cnidarians. They are
major marine predators, with integrated neurosensory, muscular and organ systems. The …

Across the animal kingdom, environmental light cues are widely involved in regulating
gamete release, but the molecular and cellular bases of the photoresponsive mechanisms …

In situ hybridization is a widely employed technique allowing spatial visualization of gene
expression in fixed specimens. It has greatly advanced our understanding of biological …

This review article gathers the available information on the use of embryo-tests as high-
throughput tools for toxicity screening, hazard assessment and prioritization of new and …

Jellyfish, with their tetraradial symmetry, offer a novel paradigm for addressing patterning
mechanisms during regeneration. Here we show that an interplay between mechanical …

The jellyfish species Clytia hemisphaerica (Cnidaria, Hydrozoa) has emerged as a new
experimental model animal in the last decade. Favorable characteristics include a fully …

Cnidarians diverged very early in animal evolution; therefore, investigations of the
morphology and trophic levels of early fossil cnidarians may provide critical insights into the …
