In real life these were vicious carnivores that would have killed and eaten a human on sight and lived mostly in shallow waters and swam up rivers looking for food they were also twenty metres long, good thing the developers didn't make them more realistic or crossing rivers would be a dream until you have a flyer.
I keep thinking I hear Lugia. Also this thing kills tusos and alpha megs easy. Only advice for alpha megs is to stay near the surface of the water for healing boost while fighting and when the Meg tries circling to reposition itself just stay where you are and let the stamina be restored. It’s not just the mouth that does damage, it’s the hips too. Might name my next one Shakira!
On The Island, I always find very quickly in the waters near South Beach, around 65 longitude. They're generally not difficult to spot, due to the swarms of Mantas and Ichthyosaurs. Though it's only happened to me once, I've found one stuck between a large rock and the beach itself, at the south edge of the rocky penninsula near 50 longitude.
Extremely op I 1v2d a lvl 125 and 95 squid with a lvl 15 raw meat tame whale. After a long fight I killed both easily. I recommend putting in health stam and melee so that u can stay under longer, stand in fights longer, and hit harder
