Ritualistic Male–Male Combat of the Northern King Cobra (Ophiophagus hannah) in Thailand

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
Following the recent taxonomic split of the king cobra complex, it is important to provide new information and context to behaviors and natural history linked to each new species. We therefore provide detailed observations of ritualistic male–male combat of the newly described northern king cobra (Ophiophagus hannah).

Review of osteoderm function and future research directions

open access: yesJournal of Zoology, Volume 325, Issue 1, Page 1-24, January 2025.
Osteoderms are bone plates in the skin that occur in virtually all major tetrapod clades. Much has been speculated about their function, but many questions remain unanswered. This review provides an overview of the current state of knowledge and future research directions in this field.

Prey specificity of predatory venoms

open access: yesBiological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.
ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.

Venom-related transcripts from Bothrops jararaca tissues provide novel molecular insights into the production and evolution of snake venom. [PDF]

open access: yes, 2014
Attempts to reconstruct the evolutionary history of snake toxins in the context of their co-option to the venom gland rarely account for nonvenom snake genes that are paralogous to toxins, and which therefore represent important connectors to ancestral ...

Structure‐activity studies of homologues of short chain neurotoxins from Elapid snake venoms [PDF]

open access: yesBritish Journal of Pharmacology, 1984
Three neurotoxin homologues (CM10 and CM12 from Naja haje annulifera and S5C10 from Dendroaspis jamesoni kaimosae) and two short neurotoxins (CM14 from Naja haje annulifera and erabutoxin b from Laticauda semifasciata)were examined by circular dichroism (c.d.) and tested for neuromuscular activity on chick biventer cervicis nerve‐muscle preparations ...

Trends in Reptile Holdings Across UK Zoos: Identification of the Factors Responsible for Declining Numbers of Venomous Snake

open access: yesZoo Biology, Volume 43, Issue 6, Page 556-569, November/December 2024.
In this study, we describe the trends in reptile holdings across UK zoos. Our results show that despite an overall increase in reptile numbers, there has been a dramatic decline in the number of venomous snakes being kept at UK zoos, and, as a consequence, venomous snakes are being excluded from many of the conservation benefits that zoos provide ...

Friends or Foes? Emerging Impacts of Biological Toxins [PDF]

open access: yes, 2019
Toxins are substances produced from biological sources (e.g., animal, plants, microorganisms) that have deleterious effects on a living organism. Despite the obvious health concerns of being exposed to toxins, they are having substantial positive impacts

Transcriptomic basis for an antiserum against Micrurus corallinus (coral snake) venom [PDF]

open access: yes, 2009
Background Micrurus corallinus (coral snake) is a tropical forest snake belonging to the family Elapidae. Its venom shows a high neurotoxicity associated with pre- and post-synaptic toxins, causing diaphragm paralysis, which may result in death. In spite

Single‐Batch Expression of an Experimental Recombinant Snakebite Antivenom Based on an Oligoclonal Mixture of Human Monoclonal Antibodies

open access: yesBiotechnology Journal, Volume 19, Issue 10, October 2024.
Graphical Abstract and Lay Summary ABSTRACT Oligoclonal antibodies, which are carefully defined mixtures of monoclonal antibodies, are valuable for the treatment of complex diseases, such as infectionss and cancer. In addition to these areas of medicine, they could be utilized for the treatment of snakebite envenoming, where recombinantly produced ...
