Venom Ontogeny in the Mexican Lance-Headed Rattlesnake (Crotalus polystictus)
TLDR
Venom samples collected from adult and neonate Crotalus polystictus from Estado de México were subjected to enzymatic and electrophoretic analyses, toxicity assays, and MALDI-TOF mass spectrometry, and a pooled sample of adult venom was analyzed by shotgun proteomics.
Venom Composition in a Phenotypically Variable Pit Viper ( Trimeresurus insularis) across the Lesser Sunda Archipelago.
The genus Trimeresurus comprises a group of venomous pitvipers endemic to Southeast Asia and the Pacific Islands. Of these, Trimeresurus insularis, the White-lipped Island Pitviper, is a nocturnal,
Insights into individual variations in nematocyst venoms from the giant jellyfish Nemopilema nomurai in the Yellow Sea
TLDR
Observations will provide a new understanding of the clinical manifestations induced by N. nomurai jellyfish stings and will therefore have important implications for preventing and treating jellyfish envenomations.
Intra-Specific Venom Variation in the Australian Coastal Taipan Oxyuranus scutellatus
TLDR
This study investigated the venom from 13 individual coastal taipans Oxyuranus scutellatus from four localities on the north-east coast of Australia, spanning a distance of 2000 km and found no evidence of sexual dimorphism in taipan venom.
Predator-prey interactions and venom composition in a high elevation lizard specialist, Crotalus pricei (twin-spotted Rattlesnake).
Individual Variability in Bothrops atrox Snakes Collected from Different Habitats in the Brazilian Amazon: New Findings on Venom Composition and Functionality
TLDR
Data obtained from individual venoms of B. atrox snakes, captured in different habitats from the Brazilian Amazon, support the hypothesis that the differential distribution of protein isoforms results in functional distinctiveness and the ability of snakes with different venoms to have variable toxic effects on different prey.

Geographic Variation in Whole Venom Profiles from the Mottled Rock Rattlesnake (Crotalus lepidus lepidus) in Texas
TLDR
Analyses using agglomerative methods (phenetic clustering methods and neighbor-joining analyses) and ordination from Principal Components analyses provide several geographically correlated groups of rattlesnake venom profiles, and evidence is provided for differences in venom profiles of geographically distinct populations.
Snake venomics of the Central American rattlesnake Crotalus simus and the South American Crotalus durissus complex points to neurotoxicity as an adaptive paedomorphic trend along Crotalus dispersal in South America.
TLDR
The increased concentration of the neurotoxins crotoxin and crotamine in South American rattlesnake venoms strongly argues that the gain of neurotoxicity and lethal venom activities to mammals may have represented the key axis along which overall venom toxicity has evolved during Crotalus durissus invasion of South America.
Venom ontogeny in the Pacific rattlesnakes Crotalus viridis helleri and C. v. oreganus
TLDR
Analysis of gut contents of museum specimens showed that lizards constitute a major fraction of prey taken by juvenile rattlesnakes, aiding in the digestion of prey in a thermally variable environment, which facilitates efficient handling of lizards and young rodents.
Diet of Crotalus lepidus klauberi (Banded Rock Rattlesnake)
TLDR
The diet of Crotalus lepidus klauberi (Banded Rock Rattlesnake) was independent of geographic distribution, sex, source of sample, and age class, but predator snout–vent length differed significantly among prey types; snakes that ate birds were longest, followed by those that ate mammals, lizards, and centipedes.
Variation in the Diet of Sistrurus catenatus (Massasauga), with Emphasis on Sistrurus catenatus edwardsii (Desert Massasauga)
TLDR
Diet is homogeneous among populations and between the sexes but that juveniles consume significantly more lizards and fewer mammals than adults, whereas both eastern subspecies favor more mesic environs and prey primarily on small mammals with juveniles occasionally feeding on snakes or lizards.
Snake venomics of the lancehead pitviper Bothrops asper: geographic, individual, and ontogenetic variations.
TLDR
This study represents the first detailed characterization of individual and ontogenetic venom protein profile variations in two geographical isolated B. asper populations, and highlights the necessity of using pooled venoms as a statistically representative venom for antivenom production.
