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!!

Plesiosaurs will team up and try to kill you

There is a group of them by herbivore island, but watch out for the Tuso(giant squid)

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 =/

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?)

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

Not once in all my time on the ark have I seen one alone, there are always two, unless you've already killed one, so watch out when taming, kill one and tame the other or tame both, just remember when you find one that another is probably nearby, ready to tear you to shreds.

If you find one, swim up until it stops going up they will refuse to swim to the surface but they still try to get you. This us how you tame them by yourself

Kill it or run the face will kill you before it does.

Lets just say watch out for thoes stupid eels..... I lost everything ughhhhh

I found this guy while riding on my mega I was shooting tranquilizer arrows at two more of these things freaking jumped me!I was like where the heck did they come from!they killed my mega I thought I was gonna get another good tame and till this day their still there I never even went into the water after that I'm basically waiting till they despawn which I bet will never happen unless I kill them myself

Try not to go too close, their will be many regrets.

I’ve often found on the island that around 2 spawn off the south-east coast of herbivore island.

A little difficult to tame but definitely worth it! I 100% recommend getting a plesiosaur I tamed a lvl 10 and its stats were very high! But if there're more than one make sure to kill one or separate them!

Good luck finding one of these they are quite rare

So the first time I saw one, I have already been playing ark for a few months and I'm like cool...they really are in Mobile.

Following real time day I am abused by two. I manage to kill them before they can kill me, okay, cool, got this.


BAM two more immediately behind them!!! Good thing I was on my basil...just barely survived the second attack

You can find 2-4 near underwater caves that are uninhabited.
