They are usually passive animals, just don't accidentally hit them. If you do attack them try and separate them from their comrades so they will be easier to kill. If you are looking for pelt, I advise using a Wolf to collect it if that's an option to you. If not, use an axe or pickaxe to collect.

I was dying from the cold already and this thing had to make death even worse. Don’t go near on

They can be found around the mountains in the winter biome if you are looking for them to kill or tame

If you ever see a Mammoth and a Rex fighting it out. Don’t get involved! 😁

Don’t underestimate deez bois I’ve seen them kill a Rex at level 25

Where there is snow there are mammoths, but also lots of danger. If you want a mammoth come prepared with as many heath Brews as you can carry and some heavy armory cause if you didn’t manage to stick your mammoth in a taming coral then you better be prepared to fend off every wolf, saber, or carno that happens Upon you. Good luck survivors!

Beware! Don’t hit I have seen one of these (low level) take on an alpha Rex and kill it!

They are slow and have a small agro radius slowing for a quick get away(assuming that you haven't lost all your stamina

You'll only find them in the snow on survival evolved.
