Well it has good loot from it if beginners like me I killed 1 today it has a advace weapons or tools on it.And also it just level 1 to 5 I just killed it by just using a bow and arrow and a tamed parasuar I'd killed it so hit the up arrow so early ark survival players can it
Just keep a slight distance away and shoot narco arrows into it's head. If you upgrade your movement speed some (idk how much exactly), you could just keep walking backwards to keep the sarco from reaching you since it never runs on land (at least none of them ever did for me).
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
