Are snakes immune to their own venom

If a snake would happen to bite its self would it be harmful for the snake? Or could a snake of the same species poison an other snake with its bite?

Snakes are immune to their own venom in their digestive tracts, as they need to digest the prey that was injected with their venom. Aside from that there is no consensus on snake immunity. Some snakes are immune to their own venom, some snakes are immune to the venom of snakes that hunt them, and some snakes are immune to the venom of snakes they hunt.

Some but not all have resistance/immunity. Most fights between the same species involve no biting due to venom being energetically expensive to make and risky to do to others.
