    To give an example of the difference in venom delivery efficiency, one can extract most of the venom from a front-fanged snake in a matter of ~12 seconds, compared to the ~20 minutes it takes to extract most of the venom from a rear-fanged snake, making the front-fanged snake venom delivery system ~100x more efficient (relative to the total ...Author: Christopher Rex

How Snake Venom Works - ThoughtCo

    https://www.thoughtco.com/how-snake-venom-works-4161270
    Jul 28, 2019 · Snake venom works by breaking down cells and tissues, which can lead to paralysis, internal bleeding, and death for the snake bite victim. For venom to take effect, it must be injected into tissues or enter the bloodstream. While snake venom is poisonous and deadly, researchers also use snake venom components to develop drugs to treat human ...Author: Regina Bailey

The evolution of venom-delivery systems in snakes

    http://www.kingsnake.com/aho/pdf/menu2/jackson2002.pdf
    Venom-delivery systems (VDSs) have evolved inde-pendently several times among vertebrates. The ear-liest known example is a hollow fang from a Triassic ‘reptile’ of uncertain taxonomic affiliation (Sues, 1991) Among living vertebrates, VDSs are found in mam-mals and squamates. Mammalian VDSs include mildly toxic salivary secretions ...

    Aug 11, 2015 · Venom evolved prior to the advanced snake radiation and, consequently, many use venom to subdue their prey. To do so, venom is injected via the use of a venom delivery system. The venom delivery system includes a postorbital venom gland on each side of the upper jaw that is associated with specialized venom-conducting fangs or teeth.
