Rattlesnakes, a kind of viper, have a very complex venom. Mostly, rattlesnake venom is a somatic toxin, which means it's not very neurotoxic, but instead attacks a lot of systems in the body.
The toxin contains enzymes that denature proteins and destroy collagen (a connective tissue) in a process that has similarity to digestion. Also, a large part of the toxin includes cellular destroyers which cause apoptosis (cellular self-destruction) and lysis (blood cell destruction). There is some neurotoxic effect in that it also contains acetylcholinesterase (ACE) that act to "turn off" straited muscles (like your arm or leg) and prevent turning on smooth muscles (like your blood vessels and heart).
There are many components and processes in viper herpetoxin that we don't understand yet.
As bad as all this sounds, very few rattlesnake bites result in a fatality, although tissue destruction (necrosis) is not uncommon in bites where toxin is delivered. About 20% of all Rattlesnake bites in America are "dry bites" in which no toxin is delivered.
It appears that the determinant factor that limits the amount of damage done in envenomating bites is the amount of time between the envenomation and medical (not first aid) treatment.
Eastern diamondback is in some areas.
The eastern diamondback is larger than the timber rattlesnake, and they would probably ignore each other in the wild.
What are abiotic and biotic factors of a eastern diamondback rattlesnake
See the image above of an eastern diamondback rattlesnake.
Yes, it is the largest venomous snake in Florida.
I have never heard of a yellow eastern diamondback rattlesnake but the average diamondback feeds on small mammals and birds.
It has diamond shaped patterns on its scale, hence this is why it is called Diamond back.
The eastern diamondback is not found in Tennessee, only the timber rattler is.
There are two species, the eastern diamondback, and the western diamondback.
dark coloured skin
Crotalus adamanteus
The pygmy rattlesnake, the canebrake rattlesnake and, possibly, the eastern diamondback are found in Louisiana. The diamondback may have been extirpated.
