Never go near it with your Dino, it will kill you, your Dino, your friends, your family, the guy down the street, some guy over in Africa, all while they won't do a thing to attack it.

Tbh, all you need to do to kill these is lure them as close to shore as you can and attack with a spear. I’d say maybe 1/30 even hit me when I attack like this, so it’s really safe. Just don’t be underwater for long around them. They look like they are moving slowly, but then suddenly you are being attacked by 4 of them.

WORST THING IN THE GAME!!!!!! They will stun your tame and kill it, regardless of the level. Only the basilasaurus is safe. If they sneak up on you with your mosasuar, they will kill you and the mosasaur

If you are reading this it seems your underwater adventure came to a shocking conclusion.

"Deepest parts of the ocean" yeah right! You run into these guys on the surface.
