“Beyond Primary Sequence”—Proteomic Data Reveal Complex Toxins in Cnidarian Venoms [PDF]
Integrative and Comparative Biology, 2019 Abstract Venomous animals can deploy toxins for both predation and defense. These dual functions of toxins might be expected to promote the evolution of new venoms and alteration of their composition. Cnidarians are the most ancient venomous animals but our present understanding of their venom diversity is compromised by poor taxon ...

Mediterranean Jellyfish Venoms: A Review on Scyphomedusae [PDF]
Marine Drugs, 2010 The production of natural toxins is an interesting aspect, which characterizes the physiology and the ecology of a number of marine species that use them for defence/offence purposes.

A Sea Anemone Lebrunia neglecta Venom Fraction Decreases Boar Sperm Cells Capacitation: Possible Involvement of HVA Calcium Channels [PDF]
Toxins, 2022 Sea anemones produce venoms characterized by a complex mixture of low molecular weight compounds, proteins and peptides acting on voltage-gated ion channels. Mammal sperm cells, like neurons, are characterized by their ion channels. Calcium channels seem

A Review of Toxins from Cnidaria
Marine Drugs, 2020 Cnidarians have been known since ancient times for the painful stings they induce to humans. The effects of the stings range from skin irritation to cardiotoxicity and can result in death of human beings.

Evolution of an Ancient Venom: Recognition of a Novel Family of Cnidarian Toxins and the Common Evolutionary Origin of Sodium and Potassium Neurotoxins in Sea Anemone [PDF]
Molecular Biology and Evolution, 2015 Despite Cnidaria (sea anemones, corals, jellyfish, and hydroids) being the oldest venomous animal lineage, structure-function relationships, phyletic distributions, and the molecular evolutionary regimes of toxins encoded by these intriguing animals are poorly understood.

Cnidarian toxins: recent evidences for potential therapeutic uses
The European Zoological Journal, 2020 Marine toxins have received global attention for their involvement in human intoxication. Many marine phyla are well adapted to produce venoms or toxins protect themselves from associated micro fauna, predators and pathogens.

Heated Debates: Hot-Water Immersion or Ice Packs as First Aid for Cnidarian Envenomations?
Toxins, 2016 Cnidarian envenomations are an important public health problem, responsible for more deaths than shark attacks annually. For this reason, optimization of first-aid care is essential.

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,
