[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.
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]
Seven different species of rattlesnake can be found across California. The most common is the western rattlesnake , which can be found from sea level to elevations of 7,000 feet, according to the ...
The tiger rattlesnake (Crotalus tigris) has a comparatively low venom yield [173] but is considered to have the most toxic of all rattlesnake venoms, and the highest venom toxicity of all snakes in the Western Hemisphere. Although reluctant to bite, tiger rattlesnakes are known to be cantankerous and aggressive.
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 ...
The Western rattlesnake is common in eastern Washington and can be distinguished by its triangular-shaped head, rattles on its tail and diamond-shaped pattern on its back. The snakes typically ...
