The only "goofy" snake I have currently is my Korean rat snake- he's a "runner" & a thrasher too- he doesn't tolerate any tight holding, but we have an understanding now- a routine for tank cleaning- & I haven't had a nip from him in years. Some rat snakes I've had start off like that, like the Taiwan Beauty rat snakes I had (more like racers) but with patience, they settle down okay- so I hate to generalize- I just try to get inside the head of whatever snake I'm holding, because they all have their own personality & perspective anyway. It helps to know what to expect from a species, but we also have to be ready to adjust our techniques. Go with the flow...when they panic, I let them "climb" thru my hands a while too.
I've never dealt with a Sri Lankan python, so I can't say that a towel method would work or not, but many snakes feel threatened when out in the open, as this one was, so it was hard to know if it was that, or being held by a strange human that was most bothersome. I'd say both. Pretty good juggling act though.![]()
