Dont let it kill you and you will live.

If you see this thing just keep swimming just keep swimming

Be sure to put your giant turtle full of c4 dodos right in its mouth to maximize your damage

This will be arks first water boss (well, not really because there’s already a water boss in ark mobile called cubozoa multis but apparently nobody cares about ark mobile)

Mosasaurs with Tek Saddles are your best bet against her, bring Megaladons for the babies.

Just don’t die to the giant coelecanthus on drugs

Mama eel is scared of an army of max mosas but you should ride a max tuso when fighting her

This thing can eat you alive so be careful

Ok well here's a REAL tip.
I suggest bringing atleast 6 lvl150 mosas for gamma.

20 lvl 150 for beta, and a few extra tames like a basilo or two, lvl 100.

25 lvl200 mosas and any other tame including lvl150 basilos.

Warning: this is a boss under water to fight use 20-50 tex mosasaurs depending on the level of both creatures.

Your gonna need a bigger tame.

Get a giant turtle and get gigas on the back, they won’t suffocate due to the bubbles so you can shred the boss with the most op Dino damage wise

This so called moeder is impossible to kill without the strongest water dino. And it is even harder to escape the moeder because she can spawn electric eels and they will try to stunn your dinosaur and kill you and your dino

Ride basils for shock protection against minions

The easiest way to kill it it will be with the basilosaurus cuz he is inmune to the stun of the cnidarias and eels

I used a couple mosasaurs with Tek saddles, a few basilosaurus, a lot of megalodons, and 1 giant turtle. Beat it decently easy. But that may just be me...

Use basilosaurus there strong and a passive tame

Shes a Giant Electric Eel, and Her Babies Guard Her Under The Sea

When you fight this bring the giant turtle it will give you oxygen when you don’t have a scuba suit also using x Megalodon‘s is recommended an x mosas I also highly recommended to fight moeder

Get 10 max level tusos and max our health and damage and you’ll take him on no problem at any difficulty. It’s how I defeated him on alpha
