Okay, afaik, there’s no listing anywhere of tensile strength of living tissues of various critters. There might be, but I’ve never run across one, and my life being what it is, you’d be amazed how often I’ve gone looking for similar information for one question or another someone asks.

That being said, I have dealt with recently dead snakes. We country as fuck up in the this piece, so we got a few snakes similar in size to a rattler, and I’d guesstimate that the average blacksnake is going to be close enough for government work to the average rattler.

So, yeah, I’d guesstimate you could strangle someone with a recently dead snake that was long enough to use as a murder tool. If you ever have to extricate a dead snake from something like a dryer vent, or the various mechanical parts of a car, you have to tug on the damn things pretty fucking hard. Even with sharp and/or hard bits involved to make holes in a snake, they don’t just pull apart. The few times I’ve had to pull a dead snake out of a car, the only thing that pulled off was whatever injury did the snake in.

In other words, if the skin and muscle are damaged enough, it’ll tear apart there. But otherwise? It’ll only come apart where it’s snagged on something, and I’m a big dude, so I can haul on things decently.

I’d say the overall toughness involved is at least similar to a decent leather belt
