DO NOT listen to the person who wrote the following comment: “DO NOT tame in the lower south cave. It will get stuck on the way out and be trapped there forever.”. If it can’t (which will most likely be the case if tamed down there, because (in my experience) Sarcos struggle just entering the cave with how wide they are. But don’t listen to that guy. Just summon it out in the “Request Creature” tab and wait for it to teleport (I have summoned creatures out of the cave when they get stuck and they teleport just fine). Share this with anyone you know who struggles with that.
I recommend taming one, they are super fast in the water, and they do a LOT of damage. I have tamed carnos and therizos but my one Sarco is the strongest one, I easily killed a megalodon and mine is only level 25, I only leveled up the stamina, speed and melee strength. Knocking it put is easy, just get it to follow you on land then throw some tranq arrows or darts to knock it out and feed it raw meat
