Toxic
Cocktails
Each animals
venom is a different mix of toxins - a complex chemical cocktail that
causes a biochemical reaction in many victims. Depending on the mix, the
victim may be paralyzed or killed by heart failure, suffocation, hemorrhaging,
or other causes.
Neurotoxins
attack the nervous system, cause muscle paralysis, and shut down respiratory
systems.
Hemotoxins
attack the blood, destroy tissues, cause hemorrhaging, and reduce blood
pressure.
Cardiotoxins
affect the heart directly.
But most
venomous animals dont envenomate when they strike a victim because
venom is biologically "expensive" to produce, taking up to several
months to replenish stores that are critical for catching food.
An estimated
25 percent of snake bites are dry, that is, they dont inject venom
into the wound. Once an animal has used its supply of venom, its
essentially defenseless and no longer has the ability to obtain its prey.
