When i was only level 4 i was looking in my inventory by the beach and one jumped out of the water at me and i didn't stand a chance. Now im level 43, i live in the southern islets and i have 13 of them. My best one is level 50 he was the second sarco i ever got and he is THE BEST. If im mounted and in the water i can kill spinos in a minute with him, once even an alpha raptor, and hes like 100mph in the water so i can travel to herbi island very fast and hunt brontos. He can pretty much take on anything except creatures that stun and dismount. Sarcos can be 100% ur best friends and hunting partners and theyre easy tames and once tamed theyre also adorable they basically allow new players to defend themselves and travel underwater
