Distinct bacterial communities associated with the coral model Aiptasia in aposymbiotic and symbiotic states with Symbiodinium

Frontiers in Marine Science, 2016
Coral reefs are in decline. The basic functional unit of coral reefs is the coral metaorganism or holobiont consisting of the cnidarian host animal, symbiotic algae of the genus Symbiodinium, and a specific consortium of bacteria (among others), but ...

Mitochondrial Genome Reduction and Accelerated Evolution in Planktonic Foraminiferans

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
The mitochondrial genomes of the eukaryotic lineage Retaria (Foraminifera and Radiolaria) show reductions in multiple gene categories, including complex I, transfer RNAs (tRNAs), ribosomal proteins, and ribosomal RNAs. In planktonic foraminifera, this reduction is even more pronounced, with the potential loss of atp and other genes.

Cytotoxic and Cytolytic Cnidarian Venoms. A Review on Health Implications and Possible Therapeutic Applications

Toxins, 2013
The toxicity of Cnidaria is a subject of concern for its influence on human activities and public health. During the last decades, the mechanisms of cell injury caused by cnidarian venoms have been studied utilizing extracts from several Cnidaria that ...

Limited connectivity of zooplankton communities across the Labrador Front: role of physical oceanography, insights from individual motility

Oikos, Volume 2026, Issue 8, August 2026.
Near the western margin of the highly productive Labrador Sea, the Labrador Current creates a large and steep oceanographic front between the Arctic‐origin shelf waters and the Atlantic offshore waters (i.e. the Labrador Front), presumably segregating or accumulating plankton communities.

Leveraging Functional Genomics and Engineering Approaches to Uncover the Molecular Mechanisms of Cnidarian–Dinoflagellate Symbiosis and Broaden Biotechnological Applications

Phycology
Functional genomics is a powerful approach for uncovering molecular mechanisms underlying complex biological processes by linking genetic changes to observable phenotypes. In the context of algal symbiosis, this framework offers significant potential for

CRISPR/Cas9-mediated gene knockin in the hydroid Hydractinia symbiolongicarpus

BMC Genomics, 2018
Background Hydractinia symbiolongicarpus, a colonial cnidarian, is a tractable model system for many cnidarian-specific and general biological questions.

Metabolic Signatures of Aging and Gametogenesis in Hydra oligactis

Aging Cell, Volume 25, Issue 8, August 2026.
Hydra oligactis undergoes cold‐induced sexual differentiation and aging, culminating in death. GC–MS‐based metabolite profiling revealed signatures of gametogenesis, for example, polyamine accumulation, and of aging, such as loss of cytoprotection and neurotransmitter function, including taurine depletion.

Along the Benthic to Holoplanktonic Continuum: Seafloor Affinity Increases Distance‐Decay Rates Among Abyssal Communities

Global Ecology and Biogeography, Volume 35, Issue 8, August 2026.
ABSTRACT Aim Marine species ranges are often large, contributing to relatively high community similarity over space, with decreased ranges expected among taxa that have lower dispersal and/or higher substrate requirements. We tested for a weakening of biogeographic structuring among dispersing abyssal taxa along the benthic to holoplanktonic habitat ...

Ancient Venom Systems: A Review on Cnidaria Toxins

Toxins, 2015
Cnidarians are the oldest extant lineage of venomous animals. Despite their simple anatomy, they are capable of subduing or repelling prey and predator species that are far more complex and recently evolved. Utilizing specialized penetrating nematocysts,

Cnidarian Toxins Acting on Voltage-Gated Ion Channels

Marine Drugs, 2006
: Voltage-gated ion channels generate electrical activity in excitable cells. As such, they are essential components of neuromuscular and neuronal systems, and are targeted by toxins from a wide variety of phyla, including the cnidarians. Here, we review
