Snakes on Trains: Railways May Sway Goa's King Cobra Distribution

Biotropica, Volume 58, Issue 1, January 2026.
Distribution of King Cobras (Ophiophagus kaalinga) across Goa, India, shows occurrence in climatically suitable forests and, notably, also along low‐suitability railway corridors, suggesting that snakes may be accidentally transported on trains, leading to range expansion.

Identification and structural characterization of a new three-finger toxin hemachatoxin from Hemachatus haemachatus venom. [PDF]

PLoS ONE, 2012
Snake venoms are rich sources of biologically active proteins and polypeptides. Three-finger toxins are non-enzymatic proteins present in elapid (cobras, kraits, mambas and sea snakes) and colubrid venoms.

Clinicopathological Features, Management, and Outcomes of Zebra Spitting Cobra (Naja nigricincta nigricincta) and Puff Adder (Bitis arietans) Snakebites in Namibia

BioMed Research International, Volume 2026, Issue 1, 2026.
Snakebite envenomation remains an important public health concern in Namibia, particularly following bites from the zebra spitting cobra (Naja nigricincta nigricincta) and the puff adder (Bitis arietans). However, the clinical presentations and management outcomes of these snakebites remain poorly characterized.

Monkeying around with venom: an increased resistance to α-neurotoxins supports an evolutionary arms race between Afro-Asian primates and sympatric cobras

BMC Biology, 2021
Background Snakes and primates have a multi-layered coevolutionary history as predators, prey, and competitors with each other. Previous work has explored the Snake Detection Theory (SDT), which focuses on the role of snakes as predators of primates and ...

Development of an Immunofluorescence Lateral Flow Assay for Detecting Four Medically Important Snake Venoms in China

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Snakebite envenomation requires rapid venom identification for effective treatment, a need unmet by current diagnostics in China. This study aimed to develop a rapid, multiplex immunofluorescence lateral flow assay for the simultaneous detection of four major venomous snakes: Deinagkistrodon acutus, Bungarus multicinctus, Naja atra, and Agkistrodon ...

Protease Activity Profiling of Snake Venoms Using High-Throughput Peptide Screening

Toxins, 2019
Snake venom metalloproteinases (SVMPs) and snake venom serine proteinases (SVSPs) are among the most abundant enzymes in many snake venoms, particularly among viperids. These proteinases are responsible for some of the clinical manifestations classically

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.

An Appetite for Destruction: Detecting Prey-Selective Binding of α-Neurotoxins in the Venom of Afro-Asian Elapids

Toxins, 2020
Prey-selective venoms and toxins have been documented across only a few species of snakes. The lack of research in this area has been due to the absence of suitably flexible testing platforms.

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
