The dossier says:
"Found only in the dark caves of the island"

They are already wrong! It should say something more like:
"Found everywhere but the dark caves of the island, this creature will gladly ruin your day by jumping out and killing you as soon as you even think about going to the swamp. Nearly impossible to tame because it has to be tamed via passive which is very difficult to do. Worst of all you need to feed them fertilized eggs. Why can't it e a little easier?

If you're in an area that has a lot of these, put stimberries in your hotbar so if you get bit, spam those so you don't knock out, if you knockout, you're dead.

Use ranged weapons against titanoboas and watch your surroundings as the can team up and knock you out.

I have encountered at least THREE OF THESE THINGS each time killing me when i try to get my stuff back lesson learned bring a bow when your trying to get your stuff back.

To the guy who said that the ark species are made up they really aren’t there almost all real Dino’s that have lived

Hate the sound they make when they are creeping up on you 😨

If it is a boa, then it should kill with constriction, now venom, boas kill with constriction, vipers kill with venom.

If you kill it and look in its inventory, its got a lot of good stuff like bows, armor, and arrows or cooking recipes. I use bows and pikes to kill them, and pack stimberries. Im playing on easy-casual on ark mobile so might not be the same for other versions.

They can climb up rocks well.
