Challenges of regulating commercial use of marine elapid snakes in the Indo‐Pacific

Conservation Biology
Marine elapid snakes are a diverse, predominantly Indo‐West Pacific species group. The persistent removal of some species has an unquantified but potentially dire impact on populations.

An in vitro α-neurotoxin—nAChR binding assay correlates with lethality and in vivo neutralization of a large number of elapid neurotoxic snake venoms from four continents

PLoS Neglected Tropical Diseases, 2020
The aim of this study was to develop an in vitro assay for use in place of in vivo assays of snake venom lethality and antivenom neutralizing potency.

Exceptional Visual‐Opsin Coexpression and Phenotypic Diversity in Outer‐Retinal Photoreceptors of Caenophidian Snakes

Journal of Comparative Neurology, Volume 533, Issue 10, October 2025.
In snakes, profound differences in retinal architecture are observed between diurnal and nocturnal species. Additionally, in the rod‐dominated retinas of nocturnal snakes, coexpression of the cone opsins SWS1 and LWS in individual cones is common, while rhodopsin (RH1) is restricted to typical rods.

Snakebites in Cameroon by Species Whose Effects Are Poorly Described

Tropical Medicine and Infectious Disease
Snakes responsible for bites are rarely identified, resulting in a loss of information about snakebites from venomous species whose venom effects are poorly understood.

Virus-like particles displaying conserved toxin epitopes stimulate polyspecific, murine antibody responses capable of snake venom recognition

Scientific Reports, 2022
Antivenom is currently the first-choice treatment for snakebite envenoming. However, only a low proportion of antivenom immunoglobulins are specific to venom toxins, resulting in poor dose efficacy and potency.

Elapid snake envenomation in horses: 52 cases (2006–2016) [PDF]

Equine Veterinary Journal, 2017
Summary Background Snake envenomation is a cause of morbidity and mortality in domestic animals worldwide. The clinical features of crotalid snake (pit viper) envenomation are widely reported and well described in horses but elapid snake envenomation is poorly characterised.

Functional Stoichiometry at the Nicotinic Receptor. The Photon Cross Section for Phase 1 Corresponds to Two Bis-Q Molecules per Channel [PDF]

, 1982
These experiments examine changes in the agonist-induced conductance that occur when the agonist-receptor complex is perturbed. Voltage-clamped Electrophorus electroplaques are exposed to the photoisomerizable agonist trans-Bis-Q A 1-µs laser flash ...

A cryptic elapid snake persists in the wake of catastrophic wildfires

Oryx
The increased severity and frequency of bushfires accompanying human-induced global warming have dire implications for biodiversity conservation. Here we investigate the response of a cryptic, cool-climate elapid, the mustard-bellied snake Drysdalia ...

Phospholipase A2 (PLA2) as an Early Indicator of Envenomation in Australian Elapid Snakebites (ASP-27)

Biomedicines, 2020
Early diagnosis of snake envenomation is essential, especially neurotoxicity and myotoxicity. We investigated the diagnostic value of serum phospholipase (PLA2) in Australian snakebites.

Surface Topography and Ultrastructure of the Spectacular Cells in the Eyes of Land and Sea Snakes (Squamata, Reptilia): Functional Adaptations of Micro‐Ornamentation

Journal of Morphology, Volume 286, Issue 9, September 2025.
ABSTRACT Although the surface micro‐ornamentation of the scales within the skin of snakes has been the subject of many previous studies, there has been little work done on the spectacle, a protective (keratinised) goggle separated from the underlying cornea by a sub‐spectacular space. The surface ultrastructure of the “Oberhäutchen” of the spectacle is
