I find one in shallow water, lagoons, rivers etc. I use my lightning wyvern to kill the mantas as the Basi takes NO shock damage. Flippers and scuba. First feed and wait 5 minutes. Also, kill everything in the area that you can. The Basi likes to wonder while you're taming it.

When taming this, be careful, Mantas and sharks follows a basilosaurus around and will attack you if you approach or feed the basilosaurus. According to the Basilosaurus dossier, Mantas usually follow them because of their eating habits (Well very messy) and it leaves plenty of leftovers for them. They attack you when you feed a basilosaurus because it leaves no leftovers for them.

I believe the dossier, but yeah.

Click the arrow pointing to the sky if useful, thanks 😊 (Sorry for the dossier spoiler)

Tame:

1. Grab an Ichthyosaurus.

2. Put Meat desired by Basilosaurus in your Hot Bar.

3. Ride Ichthyosaurus.

4. Put Basilosaurus-desired Meat Type in Basilosaurus's mouth.

5. Repeat.

6. When tamed, Megalodon/Mantas/Ichthyosauruses-in-wild will follow Basilosaurus.

7. Once Basilosaurus is in a safe spot, Basilosaurus can kill predators.

8. PROTECT ICHTHYOSAURUS FROM CARNAGE!!! I MADE THAT MISTAKE AND REGRETTED IT.

Ride dolphin or manta, water creature won't attack you while riding a water dino, then go near basilo feed it, Don't unride or you'll see your self dying, put food on your hot bar then click it when near basilo u can feed basilo without unriding. Up! So no noobs will be eaten by manta or megalodon lol

NEED TO KNOW BEFORE TAMING!

Okay, so I saw one in a river opening on Crystal Isles. I thought the mantas attack you as soon as you go near. So I slowly approached the tail near the river bank. The mantas didn’t agro on me, I thought I was just far enough away. No. Oh no no no noooo. It turns out the mantas ATTACK the second you feed it. Please don’t do what I did haha

P.S I lost my otter to the mantas. R.I.P

This creature is so easy to tame. All you need is:

1. An Ichthyosaurus(these guy won't be attack by any water creature, except the jellyfish)

2. Anykind of meat(I suggest using prime meat and don't use fish meat)

3. Find one of these creature

4. Feed it prime meat(It's a long time between the 1st and the 2nd feed, after the 2nd feed it's fast)

And then you get one of these, just be careful of the megalodons, they will attack right after it is tamed. I hope this is useful for you<3

For Fjordur players:

DON'T USE SANGUINE ELIXIR!!!

It does not work underwater, tame it with 6 kibbles

Fun fact: the first time you feed it, it takes a while. The rest of the time, it’s much faster, don’t worry!

Ignore posts about taming bar going down, you need to tame it using only the food you give it from the start, if you change the type of food you give it, it then resets the taming bar
