Tamed a level 145 by carrying with argy from swamp to my base. Picked it out the water pretty easily. Whilst it was starving, I went for another... was carrying it out and it somehow managed to dismount me when I was carrying it! I feel into the pond below the floating island on the Center map. Got killed by a pack of megalodon and mantas. My guess is that the way the argy held it meant it could dismount me. Don’t underestimate it!
My tribe lives right outside the swamp biome and these damned things are a Menace. They've killed my members dozens of times and they surrounded our mounts and killed them. Do not take them lightly they are cold blooded killers and are efficient at it.
