Tamed a level 150 by accident and boy I tell you this thin is a literal beast melee 400% from the start with 26000 health no need to put any levels in movement speed just weight if your going oil farming under water.
For those who ate looking for a travel mount this is the best choice for you even a level 10-20 can out run a Carno or rex's it literally one of the best mounts in the game.
Found four gigas and didn't tame any when I had the chance but I found an apprentice giga saddly at level 60 after completing the strong cave and now I can't find a giga to tame.
I wanted to tame one high level mosasurus but all I could find was alfa's I literally found seven alfa in the same ocean strip near the red obelisk lucky I had a pleasusur with good melee and desemated them all.
