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.

Peering into the unknown world of amphisbaenians (Squamata, Amphisbaenia): A summary of the life history of Amphisbaena alba

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.

Preclinical testing of Peruvian anti-bothropic anti-venom against Bothrops andianus snake venom

Toxicon, 2012
Bothrops andianus is a venomous snake found in the area of Machu Picchu (Peru). Its venom is not included in the antigenic pool used for production of the Peruvian anti-bothropic anti-venom. B. andianus venom can elicit many biological effects such as hemorrhage, hemolysis, proteolytic activity and lethality.

Venom Composition of Neglected Bothropoid Snakes from the Amazon Rainforest: Ecological and Toxinological Implications

Toxins
Snake venoms have evolved in several families of Caenophidae, and their toxins have been assumed to be biochemical weapons with a role as a trophic adaptation.

Secretory Phospholipases A2 in Plants [PDF]

, 2019
Secreted phospholipases (sPLA2s) in plants are a growing group of enzymes that catalyze the hydrolysis of sn-2 glycerophospholipids to lysophospholipids and free fatty acids. Until today, around only 20 sPLA2s were reported from plants.

Sequence and phylogenetic analysis of viper venom serine proteases [PDF]

, 2012
Snakebites are a major neglected tropical disease responsible for as many as 95000 deaths every year worldwide. Viper venom serine proteases disrupt haemostasis of prey and victims by affecting various stages of the blood coagulation system.
