Distinct animal lineages have convergently recruited venoms as weaponry for prey capture, anti-predator defence, conspecific competition, or a combination thereof. Most studies, however, have been primarily confined to a narrow taxonomic breadth. The venoms of cone snails, snakes, spiders and scorpions remain particularly well-investigated.

Venom is a dynamic trait that has contributed to the success of numerous organismal lineages. Predominantly composed of proteins, these complex cocktails are deployed for predation and/or self-defence. Many non-toxic physiological proteins have been convergently and recurrently recruited by venomous animals into their toxin arsenal.

Interpopulation venom variation has been widely documented in snakes across large geographical distances. This variability is known to markedly influence the effectiveness of snakebite therapy, as antivenoms manufactured against one population may not be effective against others. In contrast, the extent of intrapopulation venom variability, especially at finer geographical scales, remains largely uninvestigated.

Background: Snakebite in India results in over 58,000 fatalities and a vast number of morbidities annually. The majority of these clinically severe envenomings are attributed to Russell's viper (Daboia russelii), which has a near pan-India distribution. Unfortunately, despite its medical significance, the influence of biogeography on the composition and potency of venom from disparate D.

Background: Snake venom composition is dictated by various ecological and environmental factors, and can exhibit dramatic variation across geographically disparate populations of the same species. This molecular diversity can undermine the efficacy of snakebite treatments, as antivenoms produced against venom from one population may fail to neutralise others. India is the world's snakebite hotspot, with 58,000 fatalities and 140,000 morbidities occurring annually.

The Common Krait () shares a distribution range with many other 'phenotypically-similar' kraits across the Indian subcontinent. Despite several reports of fatal envenomings by other species, commercial Indian antivenoms are only manufactured against . It is, therefore, imperative to understand the distribution of genetically distinct lineages of kraits, the compositional differences in their venoms, and the consequent impact of venom variation on the (pre)clinical effectiveness of antivenom therapy.

Background: Snakebite in India causes the highest annual rates of death (46,000) and disability (140,000) than any other country. Antivenom is the mainstay treatment of snakebite, whose manufacturing protocols, in essence, have remained unchanged for over a century. In India, a polyvalent antivenom is produced for the treatment of envenomations from the so called 'big four' snakes: the spectacled cobra (Naja naja), common krait (Bungarus caeruleus), Russell's viper (Daboia russelii), and saw-scaled viper (Echis carinatus).

Article Synopsis
  • - Venom systems, which aid in predation and defense, have evolved across different organisms, yet various groups, including venomous mammals like shrews and solenodons, are still under-researched.
  • - The study focused on the endangered Hispaniolan solenodon, analyzing its venom by constructing a genome to identify toxins and assessing their evolutionary implications and functionalities, revealing that its venom contains specific serine proteases causing hypotensive effects.
  • - The results indicated that solenodon and shrew venoms evolved independently from a common ancestor, signifying four independent origins of venom in the Eulipotyphla order, highlighting an instance of convergent evolution where distinct species developed similar functions despite differing genetic backgrounds.

The medically important Indian red scorpion, , is one of the most poisonous scorpions of Indian subcontinent. We studied the haplotype diversity in eight populations of based on mitochondrial cytochrome oxidase subunit I (COI) partial gene sequence. Analyses revealed 22 haplotypes with a haplotype diversity of 0.

Comprising of over a million described species of highly diverse invertebrates, Arthropoda is amongst the most successful animal lineages to have colonized aerial, terrestrial, and aquatic domains. Venom, one of the many fascinating traits to have evolved in various members of this phylum, has underpinned their adaptation to diverse habitats. Over millions of years of evolution, arthropods have evolved ingenious ways of delivering venom in their targets for self-defence and predation.

Scorpions of the family Buthidae are widespread species in India. While studies are available on diversity and distribution of Indian buthid scorpions, no information is available on the phylogenetic relationships among the members of the family, within India and Asia in general. In the current study, we provide the first molecular phylogeny of buthid scorpions from central western India based on the mitochondrial cytochrome oxidase subunit I (COI) gene.
