Good mount to take into rivers and even the ocean. Good for hunting fish and I've even seen it beat a megladon. But never use it to fight a Rex because if things go south it is a very slow land mount. Short and sweet it is a hunting mount
A swift and tough mount, even on land. Even faster in the water.
Attack speed is slow, and the attack range is a small, wide cone, so enemies that are next to its neck tend to not get hit, but keep the enemy a bit further forward and the sarco will be capable of killing it quickly.
Will get stuck on trees easily, can't fit through standard dinosaur gates, and will take wide turns when following.
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.
It's better to tame one you find at a beach/river than one in the swamp. The swamp has a lot of dangers that can make taming in there a nightmare (namely titanboa and other sarco, but leeches are not fun either)
You can find them near pretty much any body of water. Sometimes they are hard to see if they are in the water. They will follow you out of the water, since they are much slower on land try to lead them away from the water.
