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!!

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

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

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 =/

WHERE DO YOU FIND THESE!?!? I’ve looked in every ocean and all I’ve found are piranhas and itchys

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

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?)

Plesiosaurs will team up and try to kill you

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

Looks kinda like the beta version of Brontosaurus tbh

I saw a group of 3 at the deep edge of the ocean on Cragg’s Island!

This…. This is the definition of plastic surgery gone wrong. Do not go to this guys plastic surgeon. -Fellow Survivor Legiana

Why no one say that this thing spawn in group..I mean it spawn 3 at one time :(

I must say when I first saw one... Well let's put it this way the dodo I had for breakfast made a reapearance.🤮 They are very creepy faces!

The real weapon of these bad boys is it’s face. DO NOT GO CLOSE! it’s so ugly it’s nightmare fuel.

I was taming a mosa with my friend and 7 of these of the these underwater giraffe cat eels came at me like the Texas chainsaw massacre guy just as scary too. What I’m saying bring and army of megladons and mantas

The most common place to find these guys is in the crystal isles in the Northwest corner of the map
