On the server I play there is this guy called ocean man and he has 2000 oxygen and is willing to tame anyone a mosa if they give him cp

Center tip: as they have added the mosa to the center I've found the easiest way to knock one out is find one close to the bubbles get its Agro and swim in the bubble the mosa will get stuck and it can't hit you. Also this gives you unlimited oxygen and sanctuary from being attacked by anything else. 🤘🏼

These can be tamed by aggroing them and swimming upwards. There is a height barrier which they cannot cross and so you can tranq them with a crossbow from above that invisible barrier.

If you have 300+ oxygen they are relatively easy. Take advantage of their bad turn radius and stick close to their tail to KO.

DONT FIGHT JELLYFISH WITH THESE I made this mistake and my 261 mosa died.

Underwater caves are very helpful for knocking these guys out. Always bring extra tranqs as this thing is basically the giga of the sea and torpor drops very fast.

Besides the giga this is the hardest dinosaur to tame, note you will need a lot of narcotics and food. Before you begin the tame I recommend at least 2 to 3 full scuba suits for obvious reasons. You need to have at least a Ichthyosaurs or Megalodon, so you can actually move around and find a decent one. Once you find one you want to tame simply start shooting at it with the crossbow. Now right when you get his attention swim up, you should notice the Mosasaurs stops following you after a certain height. The Mosasurs cannot go higher than wherever it stopped. So simply park your water Dino above it and keep shooting it. If it runs off keep doing the same thing over and over again. Sooner or later you will take him down. Good job! Then simply use this app to figure out how many narcotics/food you will need to tame it. Once it is done enjoy your king of the water.

Getting enough quetzal kibble to tame one of these bad boys can be hard to come by. Starve the mosa, and have sheep waiting at the surface, you can kill them for mutton to feed the mosa.

I think everyone knows this but still reminding that mosa has a water depth limit which it can't cross and come more higher in wild.... just use that to tame and can stay closer to him

I've found that the easiest and fastest way to knock one out is to get its attention and swim through a gap in those large underwater stone formations,it will follow you and get stuck allowing you to shoot it as many times as needed

There is crystal cave on Ragnarok around 12,23ish where you can trap the mosa, I use a ichy to trap them as they are small enuf to get in the sallow area but the mosa can’t so they get stuck👍... hope this helps

Use a squid to bring it to the surface it doesn't attack when close to surface

JUST KEEP SWIMMING!!!!!! JUST KEEP FU**ING SWIMMING!!!

Take an ichy. Get your best xbow (I prefer xbow because it’s easier to shoot and hit target on the back of the ichy) circle the mosa firing away. The ichy is quick enough to dodge the bite. If you dodge a wrench you can dodge a mosa.

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

If you live on herbivore island or another aquatic location I recommend taming one for base protection and naval superiority

We tamed a 145 with quetzals kibble and it is a beast.keep your distance and swim up

Giga of the sea. Put spikes on the plat... The attack motion gives it more effect.

Well if they took that height limit off the wild mosa no one would ever go into the ocean again. Duna duna it that jaws no its a mosa everyone run.

Swim in circles around it with a baryonyx and shoot from your mount.
