On rag they are usually on the corners of the map

If you have one of these NEVER put these guys on neutral, they will run away if it gets attacked and you’ll never see your mosa again.

(Mobile) You set sail to die, I mean tame a mosa. First you find one. Then make a cage without angering your surrounding wildlife. You die because you are too low level and you try again later. You finish the trap (4 behemoth gates closed on the ends.) Open one end swim through with you god chasing you. If it is trapped you can swim out through the side and close the gates. And then you shoot till its out. Keep it asleep with narcs or bio toxin while taming with kibble or prime. After a grueling amount of time fighting everything off. If you succeed you will have your new giga of the sea.

We tamed a Tusoteuthis and it is able to grab a mosa and keep it still. The Tusoteuthis also does torpor damage so it is very easy to KO. It can't attack while being held either

Lure it to a underwater resource cave and place a behemoth dino gateway and a gate it will get stuck ( works on mobile) tamed this at a resource cave near 87.4 and 87.5. Can be found near carno island

Have a fast mount to swim away from the mosasaurus.

They are found in deep waters near the edge of the world they don’t have a large agro range you don’t need to need to worry about them attacking

Wow... OH hello! So these giant sea creatures have massive turning circles! You can stay in their blind spot and shoot at them with harpoon and tran bolts. If you must bring a dino, turtles turn to slow. Alligators

Turn to fast.

If you combine this or any underwater platform mount you can make an actual oil rig with dunkleostrus to get oil and smelted on your platform mount if you dont have a platform mount an underwater cave works tio would recommend one next to a drop for better farming

In Genesis, there is a section underneath the Ocean E spawn where there is a glitch pass the big tek door that allows u to swim inside. I baited a mosa inside there and placed one behemoth stone gate down on him and tranqed from the top of where my base is on land shooting down on him. Yhere is currently another one there as we soeak but it's 4am and I make 9 lol

Do you think there should be shock tranq spear bolts as the underwater shock dart?

They are impossible to find in the island

Ok so if u find one of these guys swim to the surface as fast as possible cause they can only go up so far and if it’s already attacking u we’ll say gn cause mosas are fast,tanky,and are practically underwater gigas so they do sooooo much damage.🗿

The alpha mosa is faster then a Tek suit under water

I play easy mode on mobile and I rode a Ichthy shot tranq arrows at it and it did not agro… I shot it 15-20 times with a master craft crossbow and it completely ignored me like I did not exist. Mosa WILL agro at a meg, plesiosaur or basil. easiest way to tame a Mosa.

It would be cool if it could come on land like a crocodile

You can use sanguine elixirs on them while you are in a vacuum compartment and they are outside

k tamed Mr snappy now for alan... nah I'll skip that.

Make four behemoth stone gates and two behemoth Gate doors. Use your underwater tame to lure it in after aggro and then just tranq em.

Bring an Itchyosaurus with you since they're pretty fast and things won't aggro it (at least on Mobile idk about PC/Console). Have a LOT of tranq/toxicant arrows, and search for your Mosa. When you find one, shoot it and let it follow you up to the surface.

Mosasaurs have a certain depth they need to be so they'll stop aggro when you reach a certain depth (near surface) and go ham with your special sleepy time ammo.

Make sure to watch its HP and Torpor so ALWAYS BRING A TELESCOPE WHEN TAMING ANYTHING! Don't kill the poor guy.

Give it some soothing balm if you can and feed it some prime fish and so on, use BIO Toxin to keep it asleep (you can get some from Cnardias probably nearby). Boom! You've got the Giga of the sea.. Sorta.

Hope this helps and good luck!
