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!!

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

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.

Don’t use it to fight jellyfishes. Just trust me.

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

Once one of my fav water dinos. Now that face haunts my dreams 😳
