Prey specificity of predatory venoms
Biological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.

Liver dysfunction in patients bitten by Crotalus Durissus terrificus (Laurenti, 1768) snakes in Botucatu (State of São Paulo, Brazil). [PDF]
, 1995 Thirty-two patients bitten by venomous snakes sixteen by Bothrops spp. and sixteen by Crotalus durissus terrificus were studied. The group comprised thirty males and two females, aged eight to sixty-three years (mean 33 +/- 15). Bromsulphalein tests were

Acta Zoologica, Volume 105, Issue 4, Page 539-550, October 2024.Abstract Capturing data on the life of fossorial vertebrates is difficult since access to the subterranean environment is made unfeasible by its density and opacity. Collecting specimens is only possible through excavation work, causing damage or even death to the specimens.

Gape‐limited invasive predator frequently kills avian prey that are too large to swallow
Ecology and Evolution, Volume 14, Issue 7, July 2024.Gape‐limited predators (e.g. snakes, many fish) are not generally expected to pose a predation threat to prey that are too large for them to swallow, but the extent to which snakes predate on prey that exceed their gape limitation remains largely unknown.

Intraspecific variation of the crotamine and crotasin genes in Crotalus durissus rattlesnakes
Gene, 2009 Crotamine is a small basic myotoxin peptide of Crotalus durissus venom, with beta-defensin scafold and variable concentration in individual venoms. The crotamine gene was mapped to the end of chromosome 2 and the signal intensity differed significantly between the two homologues.
