These guys are your worst fear when in deep water, I was diving on a plesiosaur and one of these guys came out of nowhere to attack me, I escaped because my plesiosaur was a high level but had I gone down on a lower level one I'd be dead, I eventually decided to go back down on my mosa and tame the thing,I grabbed my megalodon as a distraction too and got all the black pearls I could carry, I dove for it and the thing caught my megalodon and I fed it, it Instatamed, I was so proud of myself, I am now the most feared ocean dweller in the server.
If yiu can tame one of these solo then it is will be an tramendous help in taming a mosa, plesi or dunkl. It is the ability to KO creatures when you grab them. Although it is my h easier to tame witg a tanky mosa already at your disposal.
If u tame one u win ark and basically life, these things are so OP u can take out any water creature including alpha tuso if you have a high level, if you manage to get one killing alpha tuso will give you a great amount of xp. Goodluck
These things are so helpful, even at a lower level. I tamed myself a level 7 (lowest on my server) and i use it to grab high level water dinos and just wait for them to KO. Managed to knock out a max level (210) mosa this morning, pulled it up to the surface, manouevered the squid so I could breathe and hen 1.5hrs later it ko'd and I tamed it up with mutton.
