I tamed this thing very recently and it was absolutely worth it. Just make sure to use a sickle to get prime meat from the sabertooth salmons so you can tame it faster. Nothing should bother you while your taming except for maybe a Carno/sabertooth or two (if you have an above level 100 tank dino you should be fine). Once it’s tamed it will be a fast, tanky beast that can breath underwater and on land!
