Shape and Size Variation in Elapid Snake Fangs and the Effects of Phylogeny and Diet [PDF]
Evolutionary biology, 2023 Recent studies have found correlations between the shape of snake teeth/fangs and diet. These studies were done at a very broad phylogenetic scale, making it desirable to test if correlations are still detectable at a narrower evolutionary scale ...

Prey transport in “palatine‐erecting” elapid snakes [PDF]
Journal of Morphology, 2003 AbstractCobras and mambas are members of a group of elapid snakes supposedly united by the morphology and inferred behavior of their palatine bone during prey transport (palatine erectors). The palatine erectors investigated (Dendroaspis polylepis, Naja pallida, Ophiophagus hannah, Aspidelaps scutatus, A. lubricus) show differences in the morphology of

Nature Communications, 2019 Antivenoms, obtained by venom immunization, have narrow species coverage due to low immunogenicity of venom neurotoxins. Here the authors immunize horses with a designed recombinant consensus neurotoxin, and the resulting antisera protect mice from ...

Generation of Multivalent Nanobody-Based Proteins with Improved Neutralization of Long α-Neurotoxins from Elapid Snakes [PDF]
Bioconjugate chemistry, 2022 Recombinantly produced biotherapeutics hold promise for improving the current standard of care for snakebite envenoming over conventional serotherapy.

A polygeneric immunogen composed of 22 venoms from sub-Saharan African snakes to expand the neutralization scope of the EchiTAb-plus-ICP antivenom. [PDF]
Toxicon XRecent research suggests that a polygeneric immunogen made from the venoms of the most medically important viperid and elapid snakes in sub-Saharan Africa could elicit a broader antibody response in horses compared to the current EchiTAb-plus-ICP ...

Fang shape varies with ontogeny and sex in the venomous elapid snake Pseudonaja affinis [PDF]
Journal of morphology, 2022 A predator's preferred prey often changes over the course of its life as it grows from an inexperienced juvenile through to a sexually mature adult. For species with highly specialised feeding strategies, this may require its anatomy to change over the ...

Two pathways for venom toxin entry consequent to injection of an Australian elapid snake venom [PDF]
Scientific Reports, 2019 Here we test and refute the hypothesis that venom toxins from an Australian elapid, the Eastern Brown snake (Pseudonaja textilis, PTx), solely require lymphatic transport to enter the circulation.

Activity of two key toxin groups in Australian elapid venoms show a strong correlation to phylogeny but not to diet [PDF]
BMC Evolutionary Biology, 2020 The relative influence of diet and phylogeny on snake venom activity is a poorly understood aspect of snake venom evolution. We measured the activity of two enzyme toxin groups – phospholipase A2 (PLA2), and L-amino acid oxidase (LAAO) – in the venom of ...

X Marks the Clot: Evolutionary and Clinical Implications of Divergences in Procoagulant Australian Elapid Snake Venoms. [PDF]
Toxins (Basel)Australian elapid snakes possess potent procoagulant venoms, capable of inducing severe venom-induced consumption coagulopathy (VICC) in snakebite victims through rapid activation of the coagulation cascade by converting the FVII and prothrombin zymogens
