As far as I know snakes don't bite other snakes of the same species, especially if they are fighting over mating rights.

They reserve their venom for hunting prey. Producing venom is a very costly metabolic process and snakes use it sparingly

I know that king cobras kill other snakes with their venom.

A search for “snake self-envenomation” will yield many examples of snakes that die after biting themselves.

Peterson, K.H. 1990. Conspecific and self-envenomation in snakes. Bulletin of the Chicago Herpetological Society 25(2): 26-28.

The reference above cites some examples. Peterson gives the following conclusions:

1. Some reported cases of fatal conspecific envenomation could have actually been caused by mechanical injury

2. In actual cases of conspecific envenomation antivenin treatment can be effective

3. In some suspected cases of self-envenomation, disease may be the actual cause of death

4. Self-envenomation is possible in some species

Also important to note that snake venom can vary widely within a single species

Self-envenomation and conspecific envenomation have been documented in a number of different species. Check out the article in the issue attached below:

Thank you colleagues,

Your submission has been helpful. I got alot of data now on the same through your guides and links.

Kind regards

if a snake is bitten by a venomous snake of another species, it probably will be affected. snakes have evolved to be immune to venom from their own species, because bites from mates or rivals of the same species probably happen fairly often.
