The influence of ecological factors on cnidarian venoms [PDF]
Toxicon: X, 2021 Venom research is often focussed on medical relevance, novel compounds and venom evolution, whilst studying the relationship between a venom and its environment – venom ecology - has been conducted to a lesser extent.

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

The cnidarian parasite Ceratonova shasta utilizes inherited and recruited venom-like compounds during infection [PDF]
PeerJ, 2021 Background Cnidarians are the most ancient venomous organisms. They store a cocktail of venom proteins inside unique stinging organelles called nematocysts.

Pharmacological characterization of cnidarian extracts from the Caribbean Sea: evaluation of anti-snake venom and antitumor properties [PDF]
Journal of Venomous Animals and Toxins including Tropical Diseases, 2018 Background Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities.

Implications of bleaching on cnidarian venom ecology. [PDF]
Toxicon X, 2022 Cnidarian bleaching research often focuses on the effects on a cnidarian's physiological health and fitness, whilst little focus has been towards the impacts of these events on their venom ecology. Given the importance of a cnidarian's venom to their survival and the increasing threat of bleaching events, it is important to understand the effects that ...

Population Specific Adaptations in Venom Production to Abiotic Stressors in a Widely Distributed Cnidarian [PDF]
, 2020 AbstractNematostella vectensisis a sea anemone (Actiniaria, Cnidaria) inhabiting estuaries over a broad geographic range where environmental conditions such as temperatures and salinity vary widely. In cnidarians, antagonistic interactions with predators and prey are mediated by their venom, which may be metabolically expensive.

Some like it hot: population-specific adaptations in venom production to abiotic stressors in a widely distributed cnidarian [PDF]
BMC Biology, 2020 Abstract Background In cnidarians, antagonistic interactions with predators and prey are mediated by their venom, whose synthesis may be metabolically expensive. The potentially high cost of venom production has been hypothesized to drive population-specific variation in venom expression due to differences in abiotic conditions. However, the effects of

“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 ...

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.
