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)

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

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

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