In my experience I have found a couple of ways of taking these big boys down easily. The first one is to utilise it's turning circle as it cannot turn fast at all, so hug it's back legs, turn with it and whack it with some sort of melee weapon at the same time, a sword or pike works best for this. The second technique is to just walk backwards and shoot it with something, preferably something damaging, so I wouldn't suggest using a slingshot here. But doing this back step technique will allow you to just be too far away from the Sarco's bite, however, be careful of what can come sneaking up behind you. And by all means do not try and out swim this thing, it will win, every time.
If u see one of these go kill it or tame it they are a pain if they are on your island I have had these constantly spawn right where I live but thankfully I set up a nice spike wall along with watch towers be careful around these AND KEEP YOUR DINOS AWAY I learned my lesson already when it took down my first Dino my otter called cuddles.... please click up to pay respects.....
my dodo (lvl 4 at the time, thought he was dead until i whistled my other dinos to follow me) was apparently in the direction of the sarco (lvl 5). he walked right into the sarco and i was convinced he was dead meat. until the sarco’s corpse just flew into the air. man, that dodo was a trooper
If you want to find one, go spawn in south 2 or go to the southern islets, they are like everywhere, I’m taming one right now, her name will be dismal ( like the Great Dismal Swamp) and she is brown on top and green on the bottom.
So I haven’t yet seen one in aberration but on the island there are easy tames. If you have a slingshot with enough rocks to knock it out your set. It’s slow on land so if you lead it out then your good. The players default speed is faster than it I’m pretty sure so I’ve actually tamed a couple with a slingshot on the island.
I was flying around on my ptero when I crashed into a waterfall my pt flew to the side and I was on a ledge. I was about to jump off when I saw a sarcho below I shot at with pistol when I fell off and thought I was dead, but I managed to kill with sword .😳
