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.

Plesiosaur always spawns with a loved one

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

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

These Guys Will eat your Barry anytime of the day so watch out while exploring to an underwater cave

Plesiosaurs will team up and try to kill you

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?)
