The Genetic Basis of Color Polymorphism in the Orb‐Web Spider Gasteracantha cancriformis

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study investigates the genetic basis of coloration in the polymorphic spider Gasteracantha cancriformis using RNA‐seq data from different female color morphs. We assembled a reference transcriptome and identified differentially expressed genes associated with known pigmentation pathways, including carotenoids, melanin, ommochromes, and pteridines.

Polymeric Nanoparticles for the Diagnosis and Treatment of Snakebite

Macromolecular Chemistry and Physics, Volume 227, Issue 1, 15 January 2026.
Snakebite envenomation affects between 1.8 and 5.5 million people annually, many of whom suffer disabilities or even death. Current antivenoms are composed of plasma‐derived antibodies. However, there remains an underexplored opportunity to utilise polymer‐based nanoparticles.

Coral Venom and Toxins as Protection Against Crown‐of‐Thorns Sea Star Attack

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Crown‐of‐thorns sea star (CoTS) outbreaks are a main cause of hard coral cover decline across the Indo‐Pacific, posing a major threat to the resilience of coral reefs. However, the drivers underlying CoTS feeding on preferred (e.g., Acropora species) versus non‐preferred (e.g., Porites species) are poorly understood. We hypothesised that coral

Evidence for Snake Venom Plasticity in a Long-Term Study with Individual Captive Bothrops atrox

Toxins, 2019
Variability in snake venom composition has been frequently reported and correlated to the adaptability of snakes to environmental conditions. Previous studies report plasticity for the venom phenotype.

Comparative Hemostatic Effects of Bothrops spp. and Daboia russelii Venoms

Biochemistry Research International, Volume 2026, Issue 1, 2026.
Venoms from Bothrops species and Daboia russelii are among the leading causes of venom‐induced coagulopathy and snakebite‐related deaths. In this study, we comparatively evaluated the biochemical composition and hemostatic effects of venoms from seven Bothrops species and D. russelii using protein profiling and functional coagulation assays.

Neutralization of snake venom by a novel polyclocal antibody

, 2022
Envenomation by the snake family Viperidae is characterized by hemorrhage, local necrosis, edema, and systemic effects such as coagulopathy, nephrotoxicity, neurotoxicity, and cardiotoxicity.

Comparative Label-Based Proteomics of Venoms from Echis ocellatus, Naja nigricollis, and Bitis arietans

Proteomes
Background: Snake envenomation is a major public health issue in Nigeria, primarily due to bites from Echis ocellatus, Naja nigricollis, and Bitis arietans. Understanding their venom composition is essential for effective antivenom development.

Animal Venom Pharmacological Resources: Exploiting Bioactive Peptides to Target Multi–Drug‐Resistant Bacteria

Biochemistry Research International, Volume 2026, Issue 1, 2026.
Background The escalating rise of multi–drug‐resistant (MDR) bacterial strains significantly threatens global health, creating a “silent pandemic” prompted by natural selection, gene mutation, and horizontal gene transfer. This crisis is worsened by the deficit in the development of new treatments, necessitating the innovative discovery of new potent ...

Animal Venoms as Peptide Libraries for the Discovery of Antiglioblastoma Agents

Biochemistry Research International, Volume 2026, Issue 1, 2026.
Glioblastoma is one of the most aggressive and widely recognized types of brain tumors, characterized by significant cellular and molecular diversity and an inherently aggressive nature. The treatment remains highly challenging, with limited effectiveness and persistently low survival rates.
