To tame this creature you need an Ichyosaurus, because nothing will attack you if you are riding it. It takes a while for it to to start the second feeding. Also, make sure you’re using the same food or the taming process will restart. A must-have to get biotoxin, because they are torpor immune. Will receive damage if you go to far down, but rapidly gains health at the surface. If playing on mobile, go to unofficial server called (Official) Pearl’s Legacy. -KingJadon08

If the basilosarus is surrounded by creatures kill them so they won’t get in your way and try to build a pen so then don’t wander off if there in a pool like the one in herbivore island

While taming the Basilosaurus you need to have a underwater dino to make it easier to swim back up and get air and the Basilosaurus is a slow taming process so do be patient.

I use an archelon to tame these. It kills the entourage, gives you oxygen, and can just roll along with the basi as you hop off and feed it

Be careful while trying to take these guys because when you try to feed them while there are mantas around it then all hell breaks loose

For the people who are having a really hard time taming this creature and it’s tame bar resetting when that happens I recommend using some prime meat and kibble anything that can make the taming percentage high I used a smoothing balm 10x in ark mobile got a 10x taming boost I just fed the basilosaures 1thrizinosaures egg kibble and it was tamed

When you feed the basilosaurus yo will notice “Red mist” come from its mouth, this must attracts nearby water carnivores like megalodon to you so be careful and maybe bring some body Guards when taming this thing

The guy who said "First make sure the area is clear" bro I spent 5 hours waiting for the area to clear.

Just get a meg or a high level icthy and lure the mantas surrounding it to someplace more open and kill them. If you kill the first lot following the basilo, another lot won't spawn and the basilo will be perfectly alone.

Keep in mind if any creature attacks the basilo, the taming will reset.

This is by far one of the best water tames, has insane health regen and if you boost melee you can easily solo kill mosa and tuso alphas, good for jellyfish because cant be stunned. And keeps you warm underwater!

The easiest way to tame this whale is to bring a Baryonyx with ya to deal with the manta's and sharks and to wear scuba gear. Once the sharks and manta are dead just passive tame the whale with either prime meat or Theriz Kibble.

So I was feeding it with the mantas still alive, that ended up with a couple of inactive specimen implants. When I finally got it, The mantas ended up killing the damned basilo. So, don't keep the manta's alive.

You can not feed basilos while riding a ichty (dolphin). You have to dismount (at least on Xbox and PS4) and if you dismount and feed the basilo the mantas will try to kill you.

Once you're able to passively feed the basil, I repeat DON'T LEAVE IT ALONE!

The first feeding is at least a 5 min wait, but once you get to the other feedings you'll have to constantly feed it every 8 seconds or else you’ll lose taming progress.

When taming the time between the first and second feed takes forever. To avoid this move well out of render and back again and it will be ready to feed 👍 Also upon your return be sure to kill everything in the area before continuing. Essentially an under water rex. great all round beast.

Try not to die when feeding it

I’m planning to tame this guy so I cannot to be scared of them

it helps people get out of fear of jellyfish

This guy does not like to swim alone so he stays with his manta friends be careful

The feeding intervals are more like 10 minutes

DodexX's Guide at taming things

Basilosaurus

Pros:

- Passive oil mine

- Immune to electric shocks (electrophorus/eel, jellyfish)

- Immune to tuso/squid hug

Cons:

- Long taming process due to the first feed in which you have to wait for its hunger bar to drop 10% to feed again

- Loses health in deep waters

- Slow turning

How to tame:

Get a good water tame (prefferably sarcosuchus or baryonyx) and get the manta's attention WITHOUT HITTING THE BASILOSAURUS, afterwards, kill all the mantas and then begin feeding the Basilosaurus, it is important to note that the time between first and second feed is long (abt 6 minutes), try to stay near your basilosaurus and kill any mantas/megs that come near it. That's it from me, bye.

Pro Tip: Basi’s won’t spawn with a whole gang of mantas on Gen 1 map, making it much easier to tame. You also have increased oxygen and swim speed in Gen 1’s Ocean Biome so you won’t need scuba gear and you can outswim Megalodons easily.
