If you you go to the the central cave on the island for the first time go by day they are much weaker, But if you cross paths with one, DON’T HIT IT!!! I learned that the hard way. I don’t ask for much but please check out my YouTube channel to get more ark tips. Thxs
Can be found in Carno island cave, south west lava cave, south east cave near Stonehenge, Central cave near volcano, and possibly others. They are very rare spawns but if checked regularly you can encounter them if looking to tame.
