They have huge hp pools, however they can get so swarmed by anglers that they get trapped inside and cannot be hit and slowly kill it. Keep a plieso or 2 on following and they can help keep your hitbox open.
Tusoteuthis
The Tusoteuthis is a massive, aggressive squid found in the depths of the oceans. In battle, the Tusoteuthis can grab its prey and knock it unconcious, siphoning its blood to gain health. Once tamed, the ink from a Tusoteuthis can be used as a constant Oil source. Some survivors choose to hunt the Tusoteuthis for its Oil.

Player-written tips for taming, using, and fighting the Tusoteuthis in ARK: Survival Ascended & Evolved.
The easiest way to get black pearls is a gasha as you can get hundreds of them and if you keep them in the crystals you won't have to worry about the wieght.
Tamed like 5 of these with a raft and 2-3 turtles
(Ark mobile)
If ur ever find one and try to tame it and it says it don't wanna be tamed Right now you need a high health dinosaur then let it grab ur dinosaur and dismount ur dino and then feed it at least 100 black pearls or prime meat.
Easy Tame, swim up with a Meg and 50 Black pearls in your food slot, let it grab your meg than jump off and swim to it’s beak & feed pearls. Easy Tuso, watch out for eels and Mosa’s.
At lat 91.1 Lon 41.0 there should be at least one tusoteuthis getting escorted by electrophagus
If you are on mobile and want to tame one you can use 10X and cooked prime meat or raw meat for a decent or easy tame
So if you need to take one of these things go on multiple failing attempts then start looking for a mosa then you will find one trust me please
If one pushes you under the mesh hop off soon as it grabs and whistle your tame passive and to follow.Or suffer the consequences.
When you see the squid............................................................gtfo
I prefer using a Pleo that’s a high lvl with over 3900 health so then u need balm and black pearls
Let tuso grab tamed at max height for tuso to swim up. Feed tuso have tame on follow swim up wait for 1000 food to burn. Don’t do the timer
Always go to the max height the tuso will swim up. Makes it easier to feed and swim up.
If u want to breed them in an enclosed nursery, it has to be VERY BIG & VERY DEEP!
im told the 'hitbox' of the baby is as big as the adult, so we thought that was why an egg wouldn't leave the underwater incubator. However, after rebuilding the space big…

im told the 'hitbox' of the baby is as big as the adult, so we thought that was why an egg wouldn't leave the underwater incubator. However, after rebuilding the space big enuf to hold 2 adults, it still wouldn't hatch @ a depth of 4 walls.
Found lvl 100 near the outer edges of the map. Wish meh luck
Why does no one use these things to tame? You can easily tame anglers or even spinos/rexes on the shore! Completely resource free! Amazing!
Life hack for PC players that don't know this yet, go to crystal isles and explore the lower beaches, you'll encounter squids beached ashore, you should have the black pearls and any tanky mount, i used my HP like rexes so it just tickled them ez.
Get your dino in…

Get your dino in between the tentacle area then punch the tuso in the mouth till it agros, then feed. I'll usually let go of your mount due to world collish but you can just agro it again when it's ready to eat. - Survivor Kure

These are a little weaker than mosas in the base damage department but they can't be grabbed by other squids and jelly stings don't eject you from the saddle like the mosa so most ppl prefer squids
Idk if anyone else has has this happened to them, but on ragnorok I found about found about 10 of these scary bastards in the top left region, 2 od which were Alphabet, unless you got your self and incredibly overpowered tuso, mosasaurus, or basil, or just an armada of one of…
Idk if anyone else has has this happened to them, but on ragnorok I found about found about 10 of these scary bastards in the top left region, 2 od which were Alphabet, unless you got your self and incredibly overpowered tuso, mosasaurus, or basil, or just an armada of one of them don't go there, the alphas apparently love to fight in packs with about 2 other Tuso's each with a couple of other random ones not too far away,so be DAMN careful!!!!
