[27] [28] However, because of its large venom glands and specialized fangs, the western diamondback rattlesnake can deliver a large amount of venom in a single bite. The average venom yield per bite is usually between 250 and 350 mg, with a maximum of 700–800 mg. [5] [29] Severe envenomation is rare but possible, and can be lethal. Mortality ...
Crotalus oreganus, commonly known as the Western rattlesnake or northern Pacific rattlesnake, [4] [5] is a venomous pit viper species found in western North America from the Baja California Peninsula to the southern interior of British Columbia.
Engelmann and Obst (1981) list value of 0.12 mg/kg SC, with an average venom yield of 120 mg per bite and a maximum record of 400 mg. [50] To demonstrate just how deadly this species is, an estimate was made on the number of mice and adult human fatalities it is capable of causing in a single bite that yields the maximum dose of 400 mg. Based ...
The most common is the western rattlesnake, which can be found from sea level to elevations of 7,000 feet, according to the California Department of Fish and Wildlife. Rattlesnakes can be ...
Rattlesnake venom is a mixture of five to fifteen enzymes, various metal ions, biogenic amines, lipids, free amino acids, proteins, and polypeptides. More specifically, there are three main families of toxins in rattlesnakes: phospholipases A2 (PLA2s), snake venom metalloproteinases (SVMPs), and snake venom serine proteinases (SVSPs). [49]
The Western terrestrial garter snake species is common in most habitats but spends a lot of time in water. These snakes are typically gray-brown or black with a checkered pattern and yellow ...
Which in turn supports the idea that predation on the snakes can be the arms race that produces snake venom evolution. [31] Some of the various adaptations produced by this process include venom more toxic to specific prey in several lineages, [30] [32] [33] proteins that pre-digest prey, [34] as well as a method to track down prey after a bite ...
