The fixed-fang snakes (proteroglypha)
are commonly recognized as having neurotoxic
venoms, but there are *plenty
of exceptions to this rule and it's very easy to overgeneralize.
These venoms affect the nervous system, making the victim unable
folded-fang snakes (solenoglypha) of
North America like rattlesnakes, cottonmouths and copperheads,
*frequently have hemotoxic
venoms. Hemotoxic venoms affect
the circulatory system, destroying blood cells, damaging skin
tissues, and causing internal hemorrhaging. It should be noted
that not all folded-fang
snakes have hemotoxic venoms. The majority of African pit vipers
the Gaboon Viper and numerous other species found around the
world are primarily neurotoxic.
poisonous snakes have both neurotoxic and hemotoxic venoms
the venom dominance can vary even within the same family of
snake. These differences within the same family of snake usually
occur due to differences in habitat or geographic location & even
prey species. It's
extremely important to not overgeneralize any species here.
For example, a North American Rattlesnake has
a dominance of hemotoxic venom, while the venom of the Mexican
is primarily neurotoxic. Again, this can vary greatly within
any species and individual. Another example can be made with
the WESTERN DIAMONDBACK RATTLESNAKE. A Western Diamondback
living in Southern California may have a different proportion
or ratio of Hemotoxic & Neurotoxic venom components from
that of a Western Diamondback living in Texas.
