An ancient pan-cnidarian microRNA regulates stinging capsule biogenesis in Nematostella vectensis.
Cell Rep, 2023 Summary: An ancient evolutionary innovation of a novel cell type, the stinging cell (cnidocyte), appeared >600 million years ago in the phylum Cnidaria (sea anemones, corals, hydroids, and jellyfish).

Trial Assay for Safe First-Aid Protocol for the Stinging Sea Anemone Anemonia viridis (Cnidaria: Anthozoa) and a Severe Toxic Reaction. [PDF]
Toxins (Basel), 2022 Anemonia viridis is an abundant and widely distributed temperate sea anemone that can form dense congregations of individuals. Despite the potential severity of its sting, few detailed cases have been reported. We report a case of a severe toxic reaction

Inhibition of Nematocyst Discharge from Pelagia noctiluca (Cnidaria: Scyphozoa)-Prevention Measures against Jellyfish Stings. [PDF]
Mar Drugs, 2022 Pelagia noctiluca stings are common in Mediterranean coastal areas and, although the venom is non-lethal, they are painful. Due to its high toxicity and abundance, P.

Cell type-specific expression profiling unravels the development and evolution of stinging cells in sea anemone. [PDF]
BMC Biol, 2018 Background Cnidocytes are specialized cells that define the phylum Cnidaria. They possess an “explosive” organelle called cnidocyst that is important for prey capture and anti-predator defense.

Variability of cnidae within a small clonal sea anemone (Isactinia sp.)
Invertebrate Biology, Volume 142, Issue 4, December 2023., 2023 Abstract The cnidom and intraspecific variability of cnidae within the small sea anemone Isactinia sp. were verified. The specific cnidae within the cnidom of four discrete morphological structures (tentacle, actinopharynx, mesenterial filaments, and body column) within Isactinia sp. was investigated.

Molecular Ecology, Volume 32, Issue 14, Page 3892-3907, July 2023., 2023 Abstract Multisensory integration (MSI) combines information from more than one sensory modality to elicit behaviours distinct from unisensory behaviours. MSI is best understood in animals with complex brains and specialized centres for parsing different modes of sensory information, but dispersive larvae of sessile marine invertebrates utilize ...

Sea anemone model has a single Toll-like receptor that can function in pathogen detection, NF-κB signal transduction, and development [PDF]
, 2017 In organisms from insects to vertebrates, Toll-like receptors (TLRs) are primary pathogen detectors that activate downstream pathways, specifically those that direct expression of innate immune effector genes.
