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? Up-vote of you agree!

There is no escape from these snakes. They spawn on every map and kill things on sight. Get this to the top so you know that they are inescapable!

The first time I made a Long Neck Rifle I found one and shot it. One bullet and one less level twelve living tranquilizer.

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.

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

Titanboas are an easily accessible sorce of raw prime meat. Keep stimulants handy!

Dude I hate these things They lit will knock you out in a hit.

You can’t go on a trip to the swamp or the caves without seeing a titanoboa

Can see you 200 meters away
Looks creepy as it comes near
One bite and you fall unconscious
Can climb over a one hight wall
Camouflage keeps them hidden
Can not fall Unconscious itself
Overall deadly.

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

So it eats any fish meat... then why does it like to eat me?

Baryonyx will mess them up. Just make sure they have a high melee stat.

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

I killed one of these guys by shooting it with arrows while walking backwards. If it gets too close, run forward a bit. Pack some stimberries in your hot bar in case it bites you.

The dossier says "found in dark caves..." Really? Have they never went to the swamp and get their A's beaten by them?

Anything that gets bit by this would get ko'd instantly! Don't get bit!

If you ever accidentally encounter these guys I say RUN RUN RUN but watch out for your stamina-But if you have a pteranodon or any flyer hop on and leave.

They live in swamps and manegrove forests

If you see one of these don't just run. Turn around walk backwards while using a pike to poke it in the eyes. Keep your distance well and you'll kill it without even taking a hit.

Complete jerks. There are always like 10 of them in south cave and with all the bugs they are just dumb.
