Medusozoans, the Cnidarian subphylum, have multiple life stages including sessile polyps
and free-swimming medusae or jellyfish, which are typically bell-shaped gelatinous …

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 are radially symmetric organisms without a brain that arose more than 500 million
years ago. They achieve organismal behaviors through coordinated interactions between …

Jellyfish comprise a diverse clade of free-swimming predators that arose prior to the
Cambrian explosion. They play major roles in ocean ecosystems via a suite of complex …

Platynereis dumerilii, a marine annelid, is a model animal that has gained popularity in
various fields such as developmental biology, biological rhythms, nervous system …

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

As the sister group to bilaterians, cnidarians stand in a unique phylogenetic position that
provides insight into evolutionary aspects of animal development, physiology, and behavior …

In recent decades, an increase in the abundance and frequency of bloom events has been
reported for the scyphozoan Rhizostoma pulmo in the Mediterranean Sea. Understanding …

Although fossil evidence suggests that various animal groups were able to move actively
through their environment in the early stages of their evolution, virtually no direct information …

During meiosis, DNA recombination allows the shuffling of genetic information between the
maternal and paternal chromosomes. Recombination is initiated by double-strand breaks …
