These guys are definitely the top 3 best tames for water. Don't waste your time with Megalodons, Kapros aren't nearly as fast (only unique factor is their ability to dismount enemies). I'd say aside from this absolute beast, Baryonyx is a good alternative. They're fast on land, have a combat buff of stunning and blinding (to my knowledge at least) and are good for cave exploration. But for real, Sarcos are the little kings of the water.
It’s easy to tame gust knock it out wile standing on a rock in a river then shoot tranqu arrows at it until it’s been knocked out then feed it meet and narcotic there amazing mounts I always use them for killing carbonemuses and other sarcos. Please like this comment guys ✌️✌️✌️👌👌👌🤘🤘🤘
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.
For any new players, if u want to tame run up to its back legs while it is on land and whack him with a club remembering to stay away from the head. U might need 2 clubs and the use of fists. Tame it away from water so it can’t swim away.
