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!!

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.

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

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

Just found one and named him nessy and he just got killed by like 13 megs

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

I found 4 at once on mobile, near the north east island and killed all 4 with my itchyosauraus

Best day ever

If you are being chased by a plesiosaur,then swim up to the surface.like the mosasaur,the plesiosaur does not swim over a certain depth limit and is never seen at the surface(bit weird since they need to breathe,right?)
