The dossier says they're passive to humans and only attack little fish THIS IS NOT TRUE THEY WILL EAT YOU AND THEY TEAM UP WITH ELECTROPHORUS TO KNOCK OUT YOUR MOUNT AND SHARE IN THE FEAST AFTERWARDS!!

THEY SPAWN IN GROUPS OF 2-3 AND CAN VERY WELL TAKE OUT A MEGALODON i put passive flee on mine and can't find it but the tribe menu says it didn't die plz brucey come backk

You're gonna need about three fiddy, then this beast will let you go.

This has to be the most terrifying creature on ark. I've tamed one and it still makes me piss my pants when i see it.

These are not "pleasuresaurs" as I soon found out =/

When on mobile please DO NOT QUIT TO SAVE THE GAME PROGRESS WHEN (plesio, tuso, mossa) IS UNCONSCIOUS, cuz it will gone and despawn

Also for someone who said you can only get mastercraft plesio saddle from "no air" pursuit, that's wrong, its depend on the difficult

easy > journeyman/mastercraft

normal > mastercraft/assendant

hard > always assendant

brutal > assendant with 3x armor

Any mobile players out there, there aren't any underwater caves so these guys are just commonly in the deep.

Whoever said plesiosaurs are the quetzals of the ocean clearly has never tamed a mosasaur

To the guy who lost his plesiosaur there's a button in menu to teleport your tames back to you but when you do it there inventory will be empty.
